The picture on the link shown above can be enlarged by clicking on it, but there is a second picture on that link that deals with the 80-82 cars. I've posted it below. Please note: The hole in the bracket on the differential must be enlarged to run the current reproduction of this part. There is no other substitute, and never run poly in this location!

Does the hole need to be enlarged to fit the bolt? The lower bushing looks flat with no protrusion to fit into the hole...

It has to be enlarged because the upper cushion has a sleeve made inside that must fit down into the bracket. The sleeve on the original 80-82 cushion was smaller, so the hole was smaller. The current reproduction upper cushion is made like the one used from 1963-1979.

Thanks Willcox.
Your most welcome... The issue is that bushing is designed to have give... and when you increase the H/P it makes it even worse on the frame bracket.
