To finish off the steering shaft I needed the column in place. Think this is the first time it has been fitted! To bolt it in I needed to refit the donor dash support frame which meant the A/C had to go in first and the brake pedal box to save pulling things to fit them later on.


Fitted the booster for the first time too and all just bolted in perfectly. The column is not only tilt but reach adjustable, I had to take both that into account before fitting the bearing support. The steering shaft actually pivots slightly through it when you adjust for tilt. I just made a simple bracket off the frame for a stronger support and to make it easier to remove the guard when necessary.


Back to the grille again. I have the turn signals chosen so had to fill in the stock holes as the new ones are a flush mount.


The filler piece I just made round and used some copper under the slots to fill them in.


Just used the mig this time as just do what my mood dictates sometimes.


Notice how much the metal rose due to the weld shrinkage. Like making a pleat or dart in material. I like to grind the bulk of the proud weld off top and bottom first before doing any hammering on it. Less material to move and the slower heat and cooling of the grinding help anneal or soften the metal a bit. Far from a full annealing process, but it can't hurt either. I dont have the weld cracking on me either during planishing.


Just by hitting hammer on dolly in the HAZ, heat affected zone, it is already almost perfectly flat.


Only now do I take the weld down to perfectly flat, because if you do that before hammering, you end up with a circle of thinner metal. Final planishing was done with a flipper and dolly.


I had spotted these turn signals on a great looking Willys Panel Delivery of Sam Hacker. He was kind enough not only tell me where he got them, but to then buy and send them to me as well.


They are a quality item with chrome plated cast steel ring and not just cheap plastic. They have 17 LED's and the circuit board is epoxy coated to keep it waterproof. Made by United Pacific to fit 39 Chevy Sedans. https://truck.uapac.com/product/cont?pid=11383


At just over 75mm-3" in overall diameter, they are between the early and later stock ones in size.


I like how they mimic the headlight bezels for shape too.


I am thinking of getting another set for the rear in both amber and red.

We are always impressed by your fab skills, Marcus, but, ahh, you installed the steering wheel on the wrong side.



Fab question for you: What do you use to grind down your welds like you did here? When I try to do this, especially on thicker material, I usually use a flap wheel on the grinder, but I wind up taking too much off and leaving an indent which always shows up after paint.

I always grind down to a razor blade thickness so as not to touch the parent metal each side with a hard grinding disc. Only then do a swap to a flap disc to make level followed by a strip disc to smooth the area. Flap discs flex too much and will take off the parent metal as well if done from the start.

More boring but necessary work going on.


Doing some more plumbing. These are the 3/8" steel OEM transmission lines. I'm just showing one of the techniques for straightening bends I use. Just clamped between some aluminium angle.


I just push a little bit at a time, then move the line in as far as it will go into the jaws each time. The squared part of the line before the bend is where the factory separation clip goes.


This is what happens if you push to far between reclamping, You get secondary bends happening causing a dog leg.


Once the bend is reduced to about 15-20*, I bend it straight in the middle of the jaws. Rotate and re clamp until it is straight all around.


Not show class, but more than good enough for what I am building. The bend was halfway between the squared part and the top bend.


The top bend was facing the wrong way. I could straighten it and then bend it the other way.


But when it has a long section before the next bend, I just twist it instead.


I now have the fuel lines run all the way as well as the transmission lines and the complete rear brake system. Still have all this to go though!


Thought I would share these hoses. They call them S hoses and are made especially for custom/universal applications.


They come in a variety of diameters and the FO on the end of the part number means these are for Fuel and Oil. They have cheaper water/vacuum versions, but you should never use them for fuel and oil!


I bought the 19mm-3/4" version to replace the power steering pump return line. You can see how much lower I have mounted the radiator than it was in the donor. It is closer as well.


I cut one of the bends off and fitted it. I was lucky with the donor top radiator hose as that just fitted right back on again. The bottom hose I had to shorten from both ends losing one of the flared end sections. I soaked the hose in boiling water to soften it and then quickly pushed it over a steel pipe slightly larger than the radiator outlet to expand it back up again. Then let cool.


Some of the more complex pipes that I was re-routing was this A/C line. I found it easier to make a template from wire first to see if I could use any of the factory bends in the new location rather than straightening it all out and starting again


This is the photo I took of the donor before pulling it apart so I knew where everything went! Even though I am making it look OEM, I try to neaten it a bit where I can.


This was I ended up with while also leaving as much room as possible for other things like the airbox and radiator overflow that was mounted on this side.


For working on the brake lines I used these tools. Rarely the centre two though as they both mar the plastic coating of the OEM lines.


I like these 3/16" line straighteners that I got from Eastwoods. I did however have to modify them so that the leading curve was at both ends rather than just one.


Just place the bend in the middle of the jaws and squeeze them hard. So long as the bend is less than 90*, they will work. Just stretch out those bends a bit first by hand that aren't.


That is the result of the bend gone between the remaining ones. I got a bit more improvement than this, if when squeezing hard, I hit the centre over the jaws with a nylon mallet while it was supported over some timber.


Lines that were shortened were re-flared with the Eastwoods tool. I was a brake mechanic many years ago and this is better than what we had back then.


A nice little trick I first saw 20 odd years ago, to separate ignition wires originally, was to use zip ties as a separation clip. First loosely loop over the two lines, then use a second zip tie around that tie between the two lines as a spacer.


Tighten the spacer zip tie fully before then tighten any remaining slack out of the other tie that is inside of it. One ready made line spacer. The line bends over the booster BTW were made with the first tool shown and the right bends were factory.


I have not done badly on using the OEM lines considering that I have 8.5" longer wheelbase than the donor Grand Cherokee and 7" of that is the front axle further forward of the firewall. Only the shortest line from the ABS pump to the nearest front wheel will have to be replaced if I want to keep the stock routing of going via the firewall first.

Wow man! You can be proud of your skills.
Thxs for the tip on the separation clip.

Keep up the good stuff.

I have a large gap to fill between the inner guard and the suspension tower.


I was first going to form the inner guard towards the tower but thought it would be better to extend the tower towards the inner guard.


This is hot rolled 2mm, 14 ga, thick steel to match the tower. I formed the compound curve inside this 150 year old gold stamper base. The multiple radiuses it has means there is always one that suits. They were there from different stamp head changes over the years of use. I just cleaned them up


I have left a gap all the way around as the tower is welded directly to the frame and the guard to the rubber mounted body.


After marking where the tower sits, I cut an even amount in from this ready for bead rolling. If you bead roll with an even amount next to it, the bead will form more consistently as it draws metal in from the edge.


I prefer to bead roll with the female die at the top in the bead roller so you can use one edge of the die to accurately follow. Too much room for error if you try to estimate the centre of the male die. So I am measuring half the distance of the die bead width from the centre of the black line.


I also turned down the flat area each side of the male die so I could get a deeper bead. For some reason the Chinese dies only the female side is full depth, but not the male side! So you can never get a full depth bead and it also means that it doesn't stretch the metal causing more distortion. I went as far as I could with multiple passes from one side before feeding in from other to complete the bead.


Still had a little stretching of the bead to do to sit flat across the top, but otherwise it did a better job.


The bead was made for two reasons. To greatly stiffen the inner guard around the opening, but also to sit some pinch weld rubber with a single top bulb in it.


The rubber seal handles all the movement between the body and the suspension tower, while also stopping road grime and track mud from coming in there.


Looks good enough from inside the guard too I think.

Nice touch. That does give it a nice finished look.

Barely took a photo as was just repeating what I did on the other side inner guard.


But look what has finally been decided on. A new set of 5 wheels and tyres! These are American Racing AR969 Ansen wheels in 17x8.5" with +25 mm offset with 5x127 PCD to suit the Grand Cherokee donor axles. Tyres are Mickey Thompson Deegan 38 AT's in 265/70R17, (31.7x10.5").


A fair bit more truck like than the stock donor ones that is for sure.


Hotrod rubber rake! Couldn't wait before finishing the front, so quickly threw on a pair of rears.


Plenty of clearance to the frame rail. I liked the tread as more old school looking like a dirt track tyre. Modern tyres would look weird and didn't want the weight and noise/handling sacrifices of a mud terrain.


No problem with clearance to the swaybar. Tyre actually protrudes a couple of inches past the side grille.


One thing that did bug me with the wheel centre moved outwards, an inch each side over stock, is that the bottom of the peak no longer lines up with the middle of the tyre.


So first thing I did was hammer and dolly out the peak that ran three quarters of the way down the guard top from the bottom of the guard lip.


Came up pretty well considering no grinding, sanding, filing or shrinking was used. Just a paint strip disc to highlight what needed to be done. I was expecting to use the shrinking disc but there was more crown at the rear of the guard where there was no peak, so it was all the same crown in the end with the peak removed.


Then I hammered out the part that dipped down to give a smooth arc instead. Then trimmed back the excess from the lip to keep it even. Guard now looks even more like a hybrid between the flat nosed 48 and the later pointy nosed guards. Also removes the troublesome stress riser that the end of the peak created where they all crack in the end. So now have both inner guards finished and changes made to the outside as well.


I had my tyres fitted without any wheel weights. I prefer on my Jeeps, and even the camper trailer, to run stainless steel teflon coated balancing beads. They don't break down like the glass ones and I have been using them for about 10 years on my Cherokee without any problems and get better tyre wear. No ugly weights to see either! See my write up on my Cherokee if you want to know more. http://gojeep.willyshotrod.com/BalancingBeads.htm


I chose these tyres and wheels for the more old school smooth sides walls matching the wheels and 48 body. I looking for a classic looking wheel so billet was out and didn't want the extra 30% heavier weight of steel. 5 slotters were even offered from the factory on the Jeep J10 which took over from this body shape. These AR969's were also offered in a satin black which would give a more military feel to the build. Turns out there were none left in the country as they are no longer produced in this size, so was lucky to get any at all. Can always paint these later along with the body if it suits better, but might leave as is.

Great choice on the wheels. Thatís a good look for the rig. Also, good call on the fender mod. Much cleaner looking.
