Thanks, it will collect dirt and the first greasy hand print I put on it because of the gritty texture but that's another reason why I painted it dirt color. I think it will hold up ok out here in the desert. Not so sure I would do it again if i was back on the east coast though due to the constant humidity where you can actually watch your jeep rust in front of you. My test panel has been sitting outside since I initially sprayed it and still has not rusted.

I'm seeing the light at the end of the tunnel. I have to figure out a way to get the jeep down to the exhaust shop so I can knock that project out.

I can just give the driveshaft shop measurements and have those made but I also want to swap out all of my yokes from the 'strap' style to something stronger also.

Rear shaft needs to be 27" and the front 31 3/16". The rear xfercase output is at a 6* drop and the rear axle yoke is at 10* rise. Hope that is workable.

Edit: just so I don't forget

The spare 80' CJ7 harness I have has a six slot/five wire plug. File/pic is to big to upload.
A-pink
B-white
C-green
D-green w/grey tracer
E-white w/black tracer
F- open

Both white wires run to the fuse panel, both green wires run to the plug on the steering column, the pink one has a push on connector at the other end. I dissected the harness and pulled it out with all the original terminals. Research time, thanks for the info yellow85cj

No work on the build this weekend but I did swap out the 'probe in the radiator' type e-fan switch for a 195* thermo switch in the back of the thermostat housing today. It grounds out at 195* and kicks on the contour fans relays then opens back up around 175* so it should keep the engine operating temp right in between. Tested everything and it works great.

The probe style switch I had in there was inconsistent. Sometimes it turned on the fans at startup when the engine was 'cold' and sometimes the probe was found hanging out of the radiator. The new switch reads directly from the coolant stream as it passes through the 160* thermostat.

The plug that was in the back of the thermostat housing had a 5/16th square recess. I was expecting a hex/allen key like I encountered on the build and of course I didn't have a 5/16th square adapter for anything. So... I ground down the lug on an old Harbor Freight 3/8 socket wrench to 5/16 and off it came. Took longer to do that part of the job than the install, wiring and testing of the new switch.

What part number is the switch you bought? I got one from AZ but don't really like it because its a stud rather than blade like yours

Maradyne MFA109. It fits in the coolant ports on the intake and also in the back of the thermostat housing.

Its wired 12v power to a dash switch then to the relays and ends at the therm switch. The fans are powered directly from the battery with separate relays which are activated when the therm switch goes to ground.

Great, thanks. That'll work better than the one I got. Kinda worried about my relays as they're only 40a each...though each relay is for only one fan, and single speed. You find a source for 70amp relays?

I had the same brackets on my e-pump bolted to the frame, it was so dang loud I took the brackets off and let the pump hand from the fuel hose.

The relays are Bosch from a late 90's caddy that I pulled from the JY. There's three on one bracket so I pull the whole bracket and cut the harness about a foot down and take all three ($1 each). Read about them in a Jeephammer post a while ago so I grab some every time I go. I forgot to mention that I use a 6 terminal power distribution block from the battery before the relays so each relay/fan has it's own fuse. There should be a video of the wire routing somewhere in the middle of the build thread when I did the contour fans on the 79'.

That's what I'm worried about. The single bracket that came with the howell kit didn't even hold the fuel pump tight. I'm thinking of cutting a strip of stall mat (1" thick rubber) and using two exhaust ubolts to hold the pump in place (body, rubber, pump, u-bracket), i just don't want to drill anymore holes in the body though. We'll see what I come up with. My holley red pump on my 79' isn't that loud, hope this one isn't either.

I swear mine sounded like the neurotic woodpecker hammering on on my rain gutter in Houston.

I was thinking about putting a rubber matt between the pump and frame as well.

Two small exhaust hanger ubolts sleeved in rubber fuel line clamping the fuel pump to the rubber mat and body is what I'm gonna try this weekend.

I tried to figure out my rear driveshaft angles using an online driveline calculator, here's what I came up with. I think I can benefit from a small spacer in the trans mount to raise the transfercase rear output and lower the front output onto a level plane. I'll have to experiment with different thicknesses of flat bar to see what gets those 6* back.

Made an uneventful trip to the Junkyard this morning and left empty handed. Not a good Jeep selection this time around. I did come across this International Harvester pickup that kept calling my name though, looks like a great project. There is something about the style of the old internationals that I really like. Everything was there and it was definitely someones project because they had their very short to do list penciled in on the tailgate and every major component was intact.

I remounted the fuel pump with the stall mat and two 1.75" exhaust hangers. My 7 year old daughter helped on this project. She got to install the nuts inside the Jeep while I was underneath pushing the ubolts through. She had fun. Hard to believe she was two when I started this build.

I drilled through the rubber and transferred the holes to the tub. Bolted it up and its done. If this thing vibrates I'll be shocked. The stall mat was 3/4" thick, not 1" like I thought, which turned out perfect because the ubolts were just long enough to pass through and be tightened down.

I've seen a 4 door international truck like that and in that color, needless to say it was sweet.

So after thinking about this IH pickup all night I decided to call the yard today and ask their price for the whole thing........and they won't sell it. Its a damn shame because it's a really nice project and I have never seen one before. Let alone seen an old unrestored truck this complete. These are the kinds of projects I like to work on, not the dime a dozen sbc swap into anything on wheels. I like the slightly odd, not too popular rides. I even found a rebuilt IH 345 on CL for it already. Oh well.
