I have a 57 BelAir 2dr HT w/502 and Tremac 5spd. The interior presently has front buckets and rear seat with roll bar. The seats are not bad just a little old and worn along with beatup door panels. I'm thinking of redoing the interior by going back to a stock bench seat and original replacement material. My question, does anyone know if the stock bench will fit with the Tremac. I have a Hurst shifter 10.5 inch curved and offset to the left. I remember way back when I put a 4 spd in my old 57. Hurst made a shifter to fit with the bench.
