    Hello there,

    I recently was under my truck (GMC-Jimmy) doing some wiring and noticed that my original rubber body mount bushings are pretty shot.

    How hard are these to swap in/out on a Blazer/Jimmy? I replaced some on my CJ-7 and it ended up being a real pain in the ass because I ended up spinning the heads off of the bolts that we housed inside the body of the jeep. It was a terrible design...! Anyway, my past experience doing this on my Jeep ended up requiring a bunch of welding and fabbing to finish the job.

    Your thoughts on ease of the installation, as well as installation suggestions are greatly appreciated. Thanks!

    On my 70 I had to cut 4 of the 6 bolts off, the other two I rung off. Went ahead and purchased all new hardware from LMC, everything that is that did not come with the Prothane kit.

    I replaced mine during a complete restoration. The nuts came off the body bolts real nice but the truck had very little rust.....could be a cuttin torch situation with rust. If the body bolts are bad or mutilated during disassembly, all the bolt heads would have to be cut out, replaced and rewelded to the floor/bed. I bought the LMC kit with rubber mounts and bolts. Installation is easy, but I think I need to shim up the mounts under the doors because after everything settled in, I'm getting some door interference (center sags). I think I would recommend a poly mount kit with the extra hardware (nuts/bolts) from LMC.

    A few of mine came out without too much work. I just had to undo the nut and grind the spot weld holding the head in place and they came right out. Some of them I had to drill the heads off them because the sleeves were rusted to the bolts and wouldn't budge.

    Mine was perrty easy too, but thats because only 5 out of the 12 mounts were actually bolted to the frame!!![​IMG]!!
    That was one of the first things I did to my Blazer. I did have to make a few trips to OSH to get the right legth carriage bolts, I used thoes nuts with the teflon lock ring on them so far they haven't loosed up on me and it's been 5yrs or so[​IMG]!
    Good Luck

    Some of mine nuts came off and some did not. On the ones that did not, I ground the whole head off and punched the bolt out from the top. I don`t see any reason to weld the new bolts . Mine were pretty rusty.

    Most of my nuts came off without a problem. Like Triaged I had one bolt that was fused to the spacer sleeve by rust. Most of the bolts were rusted down to less than half of their original strength, so I replaced them all. I should have done stainless, but I couldn't get those right away, so I ended up with Gr. 3 mild steel.
