I have never been under a 55 T Bird. If the frame is similar to a sedan, its an easy fix if you plan to keep the car. I have a 312 engine in my 55, and had an overdrive, then an SROD, and now have a T3550. To fit the 3550, (as big as the Tremmec 500 and 600), I cut the center crossmember out, then welded flanges on it so it could be bolted back in. Something the factory should have done but didnt. I have four 5/16 grade eight bolts on each side holding the center in. Durring the past 12 years it has never come loose or caused any trouble. It has been driven, drag raced, and run the one mile at Bonneville, so its not a garage queen.
