    I still can't get over how good the body is on my 67. Not a brag I just got lucky for once but I was lying underneath it the other day looking around and noticed that the pads between the tub and the frame are little blocks about 2"x 3" of 1/2'' plywood painted white. This made me wonder if they are factory or possibly an indication of a replacement body somewhere in the Jeeps past?

    Factory are rubber/fiber. Looks a lot like a piece of tire.

    I believe wood was OEM. Tire sidewall was used also.

    Been discussed here in the past, others will klnow more about particular applications.

    I don't think it was ever plywood, but oak was used, especially in the hat channels in various locations, and the spare tire rubbing block.
    As mentioned above, corded rubber (like tire sidewall) about 1 1/2" x 3" by 1/4" thick was pretty common as a body pad.

    My '68 is largely original (but not pristine) and has the OEM body mounts made of tire sidewall/tire tread/multiple layered rubber and polyester fiber "plys".
    They are of a uniform size, not sure what though dimension-wise. They're a bit stiff and crusty---would be neat to replace them with the same stuff.

    The replacements I put away at the Jeep dealer - direct from the Jeep Corp parts warehouse - were unmistakably tire sections. If you want, you can cut sections of tire sidewall with a jigsaw and fine metal cutting blade. Punch a hole in the center with this punch set Hollow Punch Set 9 Pc - should work. The punch set is very handy for making gaskets too.

    IIRC the replacements sold by Walck's are made of corded rubber sheet, not tires. McMaster-Carr Infinitely more expensive than free tire sidewall. If you'd rather, buy a sheet and cut with scissors or snips.

    I'm butchering an old tire for my replacements, because I can, and I'm kinda cheap sometimes :D

    If that's the case then I suspect it is a replacement body and fenders. Is there anyway to identify a replacement tub?

    Hey now, you gotta make another thread for that. You don't get any two-fers here.[​IMG]

    It's not likely anyone able to answer that question will see it here. [​IMG]

    If it doesn't pan out here I'll try that.

    BTW why do you have better smilies than the rest of us? :D

    It's because I have the Elite ECJ5 membership package. [​IMG]

    I wonder if you can edit the title of the thread for your two questions---like, add "and How to ID"?

    Looks like he's cutting and pasting images (the smilies) into his text. Note that the background stays white when you quote him.

    Mine are like everybody says, they look like they were cut out of a tire side wall. But I find it hard to believe that the factory had somebody setting around with a saw cutting up old tires for there mounts. :susp:
    When I replace my original ones I had a friend that worked at a coal mine that had big conveyer belts and he looked at my original ones and brought me home a piece of conveyer belt that looked almost identical to my old ones and so that is what I made mine out of. I suspect the factory made them out of something very similar.;) You can cut up the material or tires like Timgr's advise. (y)

    Today I worked on wiring, getting rid of a stereo system I didn't want and cleaning up some bad splices so I had my head under the dash a lot which brought me to the conclusion the body is a replacement and the plywood mounting blocks are not original. The body area under the dash on most any vehicle is almost never painted from the factory and that area is always covered in a light coat of surface rust. My Jeep is shiny and clean in that area something I don't think possible for being 50 years old so I'm almost certain now the tub is a replacement.

    Why wouldn't you just use the poly urethane body mounts that are available? I used them and they worked great. I bought the red ones and decided not to use them and bought the black ones. Anyone want the red ones, pm me and I will send them to you.

    Why not just use a sharp hole saw to cut them out and then redrill the center-or use a larger pilot drill in the saw? I put a 1" tub lift on my 3B and made all the mounts out of medium hard polyurethane rod (2" dia). I made them on the lathe and it was very simple. Absolutely no problems in the 11 or so years they have been on there.

    Many possibilities. The tire material is cheap (free) but may be hard to work with. You could buy Delrin sheet (a very tough and flexible plastic) and use that - I'm sure that would work fine. Or polyurethane. I expect Walck's chooses the rubber material to resemble the original parts.

    The Jeep OEM parts looked like they were punched out. Would be easy and fast if you had the right machine with a punch and die. But I expect it would take a powerful machine to punch through a tire.

    Just to follow up on characteristics of replacement body tubs, there may be a few way to determine this. First, do you have "JEEP" embossed on each side between the door opening and front fender? Are the letters all capital?
    Next, look at the area around the windshield lower hinge, on the side portion of the body there is a somewhat rectangular small panel where the side of the hinge mounts. Is this small panel flat/flush with the surrounding body below it, or does it have a slight embossed recess compared to the adjacent body?
    Most reproduction tubs have an embossed recess like those found on the AMC intermediates. The Kaiser-era tubs are flush with the adjacent body panels.
    Just a couple clues, but not written in stone.
