    I'm trying to put Humpty-dumpty back together again and it would help to have the measurement from the back-top of the tub where the tailgate hits strait forward to the top of the cowl/dash. That or whatever similar measurement people use to know if the cowl is canted properly with respect to the base line of the tub.

    Mine is a '66 and I'm wondering if the 1/4" body to frame mounts are correct for my application, it looks more like I'd need 1/2" pads? I got it with a mix of old 1/2" pads and chunks of tire sidewall.

    Thanks folks.

    I believe the originals are 3/8" thick rectangular reinforced rubber pieces. The round urethane replacements are 1/2" thick. Either way, they are all the same thickness.

    When I replaced the cowl on my Jeep, too many holes in firewall from PO, I bolted 1"X1" box tubing to the cowl where the dash bolts on. I then welded 1"X1" box tubing from the dash along the top of the box, so when I cut the tub at the bottom of the door opening, I unbolted the box from the cowl, and then bolted the new cowl to tubes where the dash bolts were, giving me the exact length I started wit[​IMG]
    h. I hope this makes sense to you, it worked out for me. My 71 box has a 66 cowl on it,

    kaiserwillys.com only sells 1/4" ones in the factory pattern and 1/2" round mounts. If the "66 used something 3/8" I'll have to make them myself?

    I like the box tubing idea but getting back to where I started isn't really a good option:

    The tire sidewall is probably original. That's what Jeep used for these insulators prior to the AMC take-over. They date back to the '40s. Walck's sells a modern replacement Body Mount Rubber Pad Military and CJ Models

    I measured both sides of 3 different CJ5 tubs, a 68, 69 and 71. Putting the end of the tape measure at the top of the cowl/dash, below the windshield frame and between the dash bolt and windshield latch straight back to the top rear of tub where the tailgate hits and they are all 5' 9 and 3/4". The tape was straight but at a downward angle as the rear of the tub is lower than the cowl. Hope this helps.

    That photo is heartbreaking btw. Vivid reminder to double check your hood latches if I remember correctly.

    Interesting example if JEEP lean.

    Wow,that was a clean Jeep, what a shame no rust, I hope everything works out for you. I would take the front end off and try and pull it back out, it is so clean it might pull out better than you think. I can feel your pain, I would like to help with that job, but I am too far away. Good Luck.

    5'-9.75" is the number I needed, thanks a lot for that! I'm 1/4" off now so time to go push on stuff a little bit.

    Yes, hood latches... plus Jeep lean, lift kit, bias ply tires, front mount winch, and that day I had removed the back seat, tools, and spare tire/gascan rack too... plus going downhill. Pretty much all the worst case situation but it still makes me sick to think of the damage.
