    1983 CJ7 rebuild has been abandoned and all parts will be sold :(

    The Goal:

    A fairly stock CJ7... don't see a lot on the road on the more anymore. Only doing a 3" lift and 33's.

    4.2L, t4, dana300, 3.31 axles

    Black interior - ??????????? exterior

    The History:

    - had a 89 yj sahara 3" leaf, 3" body, 33's, american racing rims, HEI distributor, custom carb, tube bumpers....
    - first daughter came sold jeep
    - didn't have any 'toys' picked up a really rough brown cj7 limited
    - picked up a green fiberglass body
    - found a better dark aqua 83 cj7 'donor' and took apart the limited for extra parts.
    - putting the fiberglass body on the better 83 frame

    The Good:

    - rebuilt engine, trans
    - too many new parts to list

    The Bad:

    -Typical cj frame repairs

    The Ugly:

    - my fiberglass body looks like the last owner was a blind woodsman judging by how hacked the firewall and other sections of the body are. Shouldn't have bought the body, may find another, may be doing some 'itchy' work on it.

    I won't bore you with the teardown, here's a pic in the foreground of the frame. I tossed the body onto another frame in the background for now.

    I'm on the frame.

    Nice looking CJ, gives me some inspiration to get back in the garage and work on mine.

    Only thing i would suggest with the welding would be to weld in some fish plates over the patched up areas for reinforcement

    That's a good idea. I'll probably fish plate at the rear, since I'm pulling a trailer. I think where I welded the inside of the frame under the rear spring front perch is okay.

    Hope you get onto the cj, don't see enough of them around any more. I'll probably have left over parts at the end of the build. I think I have enough to build two complete cj's LOL.

    Good idea, but I need a couple of holes for my trailer hitch, but I will be drilling a hole in the crossmember so I can hose out the frame when it gets filled with crap.

    Thanks to all for the kind words,

    I need the encouragement at this point, I found out last night that my frame measurements were way off and I have to cut off the rear crossmember that I just welded to spread the rear frame apart so my springs will be parallel.

    OffroadDaddy - I still have your emergency brake pedal for when you need it. I also have cables for you now, so I have everything except the parts inside the rear axle drums. Let me know when you want to come out.

    Spent the day with my friends grinder, sawsall and air chisel. I got the rear crossmember back off.

    One step forward and three steps back. Oh well, here's some pics.

    There's a couple of pics when I was moving the nuts in the frame to the proper location. I want to make sure the spring mounts are lined up.

    Good work!

    If I was a Jeep, they'd have parted me out a LONG time ago.

    Looking good! From the pics it looks like your starting with a pretty good CJ frame, be sure to check around the main eye spring hangers closely for cracks. They like to split where the factory welded the two halves together.
    Don't let fear and common sense get in your way.

    Thanks gents. I got out the hydraulic jack and easily made the 38 3/4" width for the outside frame rails.

    I will look for the cracks. Is the cracking normally between the outside and inside rails or where the inside rail is spliced together at the rear hanger.

    Or is it around the front hangers?

    I'm almost thinking of starting a frame measurement post and common problems for the cj, yj, tj frames.

    I hope that 38 3/4 is a typo! The dimension is supposed to be 37 3/4
    As far as the cracks go they usually start at the spring hangers and run longitudinally along the frame where the seam of the inner and outer frame rails meet on the bottom of the frame. Also check for cracks running vertically just behind the front main eye spring hanger as well.
    Just for clarification check around the hangers that hold the main eye for the spring. Don't usually see cracks at the shackle hanger end but it is possible. Usually rust at the rear is the problem which you obviously know about.

    38 3/4" I meant 37 3/4" .... The coffee hadn't quite kicked in yet. LOL I will take a close look for cracks before the finishing stage. I'm willing to go the extra mile to make sure I have a solid foundation.

    I think I will be adding fish plates on the outside just to ensure strength.

    All hail 37 3/4"............. and the hanger bolts are smack on 36". I was definitely worth re-doing.

    Next step, a little grinding and some fish plates.

    Is the plate in the last picture factory, or was it from an old trailer hitch. It goes between the frame and rear crossmember on the gastank side.
