Where can I find correct big block frame pads for a ‘71 Cutlass?

I’m trying to mount the Inline Tube solid motor mounts for a 455, but car has small block frame pads (factory 350 car that I have swapped a 455 into).

Thanks.

 

There are only two frame pads for the A-body cars, the ones you have and the so-called "big block" pads. You need the latter, used on the 1969-72 BBO A-body cars. Type 2 in this photo.




Here is a side-by-side comparison. Your current ones are on the left.

 

Thank you Joe. I’m curious if any of the offerings on the market from certain vendors are superior to others, or are they all virtually the same. Fusick had best price on my limited browsing.

 

All the repros likely come from the same factory in China. I wouldn't sweat it.
