I had a 71 10 bolt Nova under my 39 coupe, then I went to a 69 Camaro 12 bolt. I have known many guys that run mid 50's chevy rear ends but those are getting hard to find. The 72 and on chevy cars are too wide and I am not sure about the S-10 but those are a smaller 10 bolt (7.5) so watch out if your going with a torque motor
