    I'm replacing the inner fender and battery tray on my 78, and the subframe bushing is in horrible shape so need to replace that too, (thanks Twisted_Metal for pointing it out in my "rusted battery platform" thread).

    Check it out...pretty nasty:


    I'm not sure exactly what I need for this...I've looked through some of the parts catalogs and I'm a bit confused on what I need in terms of bolt(s), washer(s), bushing(s) and biscuit(s)...

    Can you guys give me an idea of what parts I need, and also any suggestions on doing the job?

    I would bet the rest of em look just like that one.
    There has been a lot of info posted on sub frme bushings here. It depends on what you will be doing with the car. There are basicaly three options. 1. factory rubber, 2. urethane, or 3. solid mounts.

    Here and there...
    You should be able to buy a kit with everything you need. For example:


    NPD, and I'm sure many other places, sell the rubber bushings. Poly will tighten up the body a little. If you ever plan on adding sub-frame connectors, install solid mounts now & be done with it. Protouring f-body (on this board) sells a nice kit with the solid bushings & all the hardware you need.

    Here is a great how to:

    Edit: PS, good luck getting that bolt out. It looks a little rough. +1 on just doing them all...

    I installed the PTFB ones a few months ago, and I am happy with the results.
    Replace them all at the same time, and from the looks of things you have quite a job ahead of you.
    Start soaking all of them with PB Blaster now, so by the time the bushing get there you will be ready to throw them on.

    Use the OEM's for street. Do a search, 67Lemanster and others did a super write up on replacing them

    That's awesome, thanks for all the info!!

    Gonna order the kit and start soaking the bolts today. I'm thinking I'll go with the poly.

    Great write-up in the other post on how to do it, (tip on jack placement is priceless). Looks like the hardest part of the job will be getting the old bolts out...
