I was able to use poly insert from second gen mounts with some trimming inside 3rd gen clam shells. And the 85 square I had use same size as a thirdgen. Not really sure on the reasoning behind those changes
I refer to the engine side brackets as the clamshells. My poly mounts were bought years ago for an '86 Z28. It's interesting, the box says they fit 2nd and 3rd gen. I guess I'll see if they need shaved when it goes together.
