motor perch problem

[dantimdad]

I went to drop the engine onto the frame today and the perches sit about 1.5" too wide.

I bought new motor mounts for a 69 chevelle because that is what the engine came out of. They look just like the ones I took out but, now I realize they are much thicker rubber.

Any clue which mounts have the same bolt pattern as the chevelle ones but are thinner?

I have the engine propped up right now so I am kinda wanting to figure this out quickly without a dozen trips to the store to swap out.

Thanks for your input!
