    I haven't been on here that much lately except to ask a few questions for friends (thank you for all the help), I thought that I would post up the build of my J-4000 to make up for my time missing, because it looked like there were a few people interested in it when I introduced it here. I hope you like it (and don't kick me off because it's not GM:o )
    Specs- 1973 Jeep J-4000, AMC 360, TH400, Quadra trac, Dodge dana 61 front (open), van width 14 bolt rear (lincoln locked), Chevy 56" rear springs mounted under the frame in the rear, 74 J-10 leaves mounted under the frame with longer shackles in the front, with a total of around 10" of lift, 39.5" Swamper TSL's.
    Here's the (kinda) finished product at a car show. Build stages to come.

    I started taking pics with a digital camera after the rear suspension was done.

    I then loosely threw the bed on, pulled the drivetrain, and mocked up the front suspension with a 10 bolt. The rear axle at the time was a SRW 14 bolt for mock up.

    I then took it to the school, welded up the front suspension, cleaned and painted the frame, installed the drivetrain, and wired the new front clip with the fender flares removed.

    I then moved on to work on the van 14 bolt.

    Then the 39.5's went on.

    Then we dragged it up the RTI ramp with my brother's truck for a flex test.

    I changed out the gears in the rear, with welded spiders. The ones I have now are 4:10s because that is the lowest that the D61 front can take without a spacer. I fitted a rear shaft and a front one, but I didn't get the front gears changed out in time for a car crush at a local car show, so I did my crushing in 2wd.

    A friend's chevy shortbed K-10 went first. I know you'll want specs, so it's a 75 with a 350, th350, np205, 14 bolt rear with a limited slip, dana 44 front (open), 4:10 gears, 4" lift as I have been told with plenty of trimming, 35x16 boggers on 15x12 eight lug steelies.

    The major casualties.
    [​IMG]
    They did strike back though.
    Later in the day, we went for a try in a T-bone fashion, every rig broke / damaged something.
    The chevy bent his tierod, broke his rear bumper off coming down off of the cars, and leaked some tranny fluid. But he was the only one to make it over.
    I locked it into 4wd, because I was slipping enough to not really hurt much. I busted my front shaft trying to hop the rear tires up. I removed it and drove home.
    The CJ failed after several flying attempts, tore off most of the exhaust.
    Here's my busted shaft. It seems that it snapped from being too brittle from the shop. My brother and I replaced it with a much better solution.

    More later.

    Thanks for the compliments. I changed out the front gears, then took it out to test a couple of times in a pasture and in a dirt filled lot. That's where I am today, just taking care of little problems as they pop up.

    :eek::eek::crazy::eek1::eek1:

    I cannot believe that you are running shackles in the front! I bet that think creeps forward at brakeing.

    Also- What size tires are you running? Otherwise looks great. We have one of those jeeps laying around.

    Having grown up with Wagoneers, Cherokees, and a couple J-10's, I've gotta say that is sweet. "... with bald tires, that old Wagoneer would go places this Bronco can't." said by the PO of one my dad had bought. I prefer my Chevys, but am still fond of them old fullsize heeps.

    Actually, that is on the side of the highway. Coincidently, there was an accident at the intersection just down the road from us, but from the angle of impact, we didn't cause it with a distraction.
    It is kinda hard to stop, but I guess that's to be expected with 100 or so pounds of tires on each corner. I chose them in the front, because it pushes the front tire into obstacles when driving.
    The tires are 39.5" tsl's.
    When I get the chance, I'm going to paint it rattle can flat black.
