Re: '75 J-20 service truck
Wow, your truck weighs double what mine does. I think mine was in the 4200 range last time I weighed it.

Very cool build. The air channel is genius.

Re: '75 J-20 service truck
Not much has happened other then driving the hell out of it and gathering parts. It's been put back into DD service since Xmas eve.
I got a set of air bags for the rear, but found a writeup for a second a.c. compressor so gathering parts to put that together before I install them.
Lost my lift pump 2 weeks ago, so got a new FASS pump, only took 20 mins to swap out. 2 screws and the plastic inner fenders come off and I have full access to the side of the block. Why can't everything be this easy to work on???
Last 2 fill ups I was averaging 16 MPG, guess I need to "try" to keep my foot out of it. It's hard when it moves this ole truck around like a sports car on crack...

Re: '75 J-20 service truck
Got to put her to the test today. Ran great, but would be looking to chip it if I did a lot of towing.

Re: '75 J-20 service truck
Seems like a fair trade, you’ll probably benefit from the new kitchen as well- happy spouse, happy house.

Re: '75 J-20 service truck
Lol, I'm lucky I have a high metabolism...
Last Friday I developed a squeak in the rear chasing parts for my wife's ZJ. Before I got home, it turned into a grinding noise and heard a couple of pops like it was spitting pieces out. Got it in the air and the pass side had come apart and ground all but 1 spring to pieces, and there were 2 flat spots on the adjuster wheel. IT IS SO BITCHIN TO GO TO THE MCPARTS HOUSE AND GET EVERYTHING OFF THE SHELF! They had a complete small parts kit and it's all New in there now.

Re: '75 J-20 service truck
How am I only just seeing this?? Thank you so much for documenting your build so thoroughly.
So after 6 months of DD, are you still happy? Anything that you wish you did/didn't?
What's the most you've towed to date?
Thanks a billion!

Re: '75 J-20 service truck
Still grinnin from ear to ear.
At this point there's nothing in what I've done I'd change, but a few things left to do. Still want to drop the front 3", but im looking for a set of stock front springs to cut. I just got a 1/2" plate of steel to build the mount for the second a/c compressor where the front engine hoisting eye is for on board air, then I have bags for the rear and air horns. I also need to get the VA system in, it's getting warm....
Hard to say on heaviest, probable the 01 v8 grand Cherokee on a tow dolly.
And last fill up I got 17.3 mpg...
God I love my truck....

Was it pretty insane to try and get her registered/insured? Is it still considered salvage?

Re: '75 J-20 service truck
It has the same Jeep VIN plate under the hood and door jamb, and I'm running the same historic plates it's always had. I just keep renewing the tags online. We are a non-emissions county now, and even if we did, it should be cleaner then the stock.

Re: '75 J-20 service truck
My trans kept leaving little drips under the rear aluminum case and the last couple weeks it turned into small puddles. Found a cast replacement on Ebay for $85 shipped and no more worrying about its fluid level. Did the seals in t case while it was out. Also found it already has a 5th gear lock nut, so that's another worry off my mind...
