OOPS!!! My apologies! You said it is a 1960 car NOT a 1970. Of course the TH350 wasn't around in 1960.
Also the driveshaft yoke will need to be changed for the TH350. Interestingly enough this is the same yoke used on the Muncies, Saginaws, and the all sychro 3 speed trannies. So down the road if you do a tranny swap from one of those to another that will stay the same.
