No Going Back now. 70 LT-1

I was shocked to learn that all of the body mount bushings are solid aluminum. I learned that before removing the body, so at least I wasn't surprosed.

Using a mic, they don't seem to be the same sizes. But.... most of them are corroded and swollen.

Were they all the same size or was there some procedure to determine how thick if a bushing to use at each mount? Forgive me if this is in the Assembly Manual. I have one, but it is down at the shop right now. Too lazy to go look.

Also, because the body was not built by Fischer, the Assy Manual is about four times the size of the Camaro AIM!!!!

Next question: is it simply anathema to use hard rubber bushings instead of aluminum? Seems like the aluminum would contribute to squeaks and rattles. You know, the Opel GT of the 60s and the C3 were designed by the same guy. I am shocked every time I drive them back to back how much more solid the Opel feels than the Corvette. That is sad.

Not an easy task you are getting yourself into. There are shims at each body mount. When you remove the body mount, DON"T lose the shims. Record and count each position. The same amount will have to go back in the same spot when you install the body back on the frame..

Yup. Eyes wide open. I knew is would be a challenge.

All the shims are simply thick aluminum washers on this car.

All are corroded to some extent, with some being worse, and several are in pieces. When aluminum corrodes, it swells.

Most of them still have remnants of paper tape that I assume helped hold them in place.

The ones that aren't swollen all mic at .385. The rest; who knows.
