I was just browsing through summit racing online today when i came across this:
Trans-Dapt Performance Products 4982
http://summitracing.com/parts/TRD-4982/
Judging by the picture, they would work for 86-88 cougar/tbirds with the 5.0, bolting to the block then using the horizontal bolt going from front to back like the stock mounts.
Looks like a winner, anyone using these?
Looking at them, I would say no, not a bolt in. Not tall enough.
It says right on the site they fit an 88 Tbird V8.
No, it says they work with their crossmember kit. It ALSO says that it's a universal kit. It ALSO says that it fits 79-93 Tbirds...which is not possible.
It's a UNIVERSAL SBF motor mount that works with their UNIVERSAL crossmember kit.
I might have a little idea about motor mounts for these cars ;) Just a hunch.
