T-Bird seat definitely different enough not to work. I did have a T-Bird LT front seat that I removed from the stock pan and switched to the America 's front seat pan and it worked well, but the pillion seat would not go on without a major mod.
I have an '08 & a '14 America and interchange seats often.
The '14 (LT) has a baronet mount though, so if you can do a little playing around with it, you'll have no problem.

The ride may be fun, but in the Great Scheme of things, it really is about the destination! John 3:16
