There are also some good TBird forums out there (Google will lead the way), I would check there and see what those guys are doing.
To answer your question though, I think it is highly unlikely that any Mustang specific sfc's will fit, they are completely different cars and TBird also has a longer wheelbase. If you were talking about a pre-1990 Bird, the answer would change to "maybe", as those cars were built on Fox based platforms like the Mustangs of the same day.
