I bought a '78 Cutlass donor car for my rod project. It was a decent runner with a 305/ automatic ( which I assumed was t.h. 350 when I bought it for $500.) I pulled the motor and trans the other day and discovered I had a t.h. 200. I have done a little research on it and have found a Transgo shift kit for it. Anyone else running one of these, and if so, are there any other aftermarket suppliers? Thanks..
