Just a brief update. I got an OBA setup on it now. I acquired a good used York from a truck at work - the driver insisted the compressor was bad and was locking up only seconds after turning the A/C on, when in fact it was a loose v-belt! He had the new compressor already, so I put it on. He didn't want the old one, so I put it on my CJ!

I had to make a bracket, there are not many CJs in the JYs around here anymore. The big scrap price jump a few years ago saw a lot of house cleaning from the yards, anything older than 2000 went to scrap. Really sucks!

I started out with a piece of 3/16 (?) steel and some cardboard, making a template and tracing it on the steel. I just used the 2 studs on the front two head bolts on the driver side.

Rough cut of the base plate after using the Oxy/Acetylene torch to cut it out and a flap disc to clean it up a bit.:

http://i61.photobucket.com/albums/h6...psa31fd62b.jpg

I was going to borrow a co-worker's plasma cutter, but he forgot it the day before and he was off the day we did this. We ended up doing this at work (we as in the service writer and I) since it was a day with no work coming in, and we were bored out of our minds - hence not waiting for the plasma cutter...

Mocked up, cut, and fine tuned the support piece. Bolted it in place, drilled the holes for the top plate, heated and bent the top plate in the vice, and set it in place to tack weld them together.





Welded both sides, he likes his stick welding. Notice the length of the support, it had to be cut down as the mounting bolts for the compressor ended up right in place of that piece.



Didn't get a pic after trimming it, but here it is installed.



A pic showing the bracket finished:

Thanks! I have some pics of the tank, mounted under the tub above the pinion area of the rear axle. I'll try to get those up tomorrow.

I pulled the valve core from the right front tire today at work, let all the air out. Took me 1.5 minutes to air it up to 35PSI, checking it every 30 seconds or so. I set the idle at 1000RPM for this test. I did it at work so I had another air compressor handy in case something happened in the test. Had no doubts though!

I'm using a 160-200PSI switch on it. I don't have a manifold for it yet - Fed Ex came while I was still in bed Friday :/ The downfall of afternoon shift and being a night owl - you miss the Santas! I'm picking it up at the FedEx store on my way to work.

Was going to add some stuff here, and realized I never posted those pics of the tank mounted.

Here they are:



The fittings and check valve looking up from under the CJ. It all cleared the frame.



Plenty of room.



I need to add a drain to it some day. It is definitely thick enough that I feel comfortable welding a bung to it and putting a drain in the lowest point of the tank.

Well, The reason I came on here today was to update it with a link to the thread where I was venting my frustrations from installing the new top. I'm not as frustrated about it now, but I am still nervous about taking it off this summer... We'll see then.

http://www.jeepforum.com/forum/f8/su...tment-2180361/

I am also starting to ponder a 2.5" lift, as with the plow and winch in the front, the bump stops are lightly touching the axle. The wife (Randi) has already said to do what I need to do, as "you know we need the plow to do my (her) Mom's driveway, and we can't have your Jeep broke to do that." So now I am looking into choices for lifts. Obviously, ride and durability are #1 concern, but I can't just get the most expensive one out there.. I think I remember it being Pro Comp who has a lifetime warranty, where if they sag or break I get a new part to replace them. Also needing new shocks (I think I have blown one recently), I need to get them. Now comes the fun of piecing a kit together... I want YJ front springs, Shocks to fit the WT axles, and new u-bolts/nuts. Also going to need to get new spring plates, as mine are warping from being reused too many times. Plus the WT shocks mean I need the Ford upper shock towers to bolt to my frame, as it was set up and currently has the NT axle still in the front.

Then comes the fact that I will need revised driveshafts, so I have to cut the spring mounts off the rear axle and rotate it to use the DC rear shaft I have. I would love to do the front as a DC too, but I am not currently up for rotating the "C"s of the front axle to adapt the pinion angle...

Then comes the thought - Well, if I have to redo the driveshafts, I might as well do the 302 swap too, since that will no doubt change my transfer case positioning and affect the drive shafts too......

Looks like I have my summer "To Do" list now.....

Now to get her to understand how all of this is needed because of my "broken Jeep to plow"....

I can tell you the 2.5" RC spring lift is ruf-as-a-cobb! But it was cheap, and it is holding up (no sag). I did it on two CJs.

AND, you should investigate a bastard pack spring lift. I did this on Fallon's XJ and gained 4". It involves rebuilding your spring pack. Cost me ~$75, including the metal cutting drill bits and longer center bolts.

OR- look seriously at YJ springs.

Nice job on the tank Bud.

Thanks!

Yeah, definitely going to go with a YJ spring in the front. I had to put washers in the front to space the shackles and mounts to fit the CJ springs. I didn't realize that when TDK does a shackle reversal in the frame they set it up for YJ springs...

302 swap...heavier axles....Ford 9" front and rear....maybe swap the transmission....Yep that's where it all starts my friend! I like the snow plow idea too.

Ok, Looking thru doing research for the YJ conversion, I was wondering if anyone could tell me the factory mounting points for the CJ vs. that of the YJ. I have front CJ springs on it now, and the shackles look to be at a decent angle, so I am thinking they built my frame using CJ length for the front but YJ width. I just need to confirm this..

Ordered my springs and all required pieces, including a HD steering shaft and also new rear axle spring perches so I can turn the axle to get the optimal pinion axle for a DC drive shaft.

Now, to seriously start the fun of piecing the parts together for the 302 swap.

I think I'm going to find a car donor, was planning on a truck donor since they are probably more abundant (read cheaper!), but then I'd have to change out the brackets and risk not fitting with the taller intake. I am confident I can handle the engine install and mating it to the transmission, adapting the clutch pivots to fit, and that stuff. There will be some questions along the way, so I'll post them here and hopefully I will get the help I need without starting another swap thread...

I think the main question I have is about the exhaust - what manifolds and possible Y-pipe can I use? I'd rather use manifolds, as they are more durable and I am not worried about all-out power anyways. I'd also like to just run a single exhaust for cost and simplicity, as then hopefully I can just reuse my cat, muffler, and tailpipe.

I have read a lot of the threads on here, and also the Pirate4x4 thread, and most seem to go with headers. I think I remember something about using 90's F150 manifolds, but I have read and reread so much that it is all just rattling around in my head in a mess now - would like confirmation...
