1962 Valiant Suspension/Brake Swap Options with other A-bodies

Yep, changeover year was 1968. 67 318 wouldn't be a problem fitting a 67 and earlier trans. 68 and later small block would require the adapter ring to fit over the earlier torque converter snout and into the back of the later crank. Or, I know the big block pushbutton trans can be fitted with a later torque converter by changing a few parts in the front of the trans case (input shaft and I can't remember what else). I've done that with my 59 Coronet (with 62 Torqueflite) and 64 Polara conv. big blocks. Probably could do that with a small block pushbutton trans, too.

273 Torque converter & transmission

I think CharlieS had those rings at one time.

Someone used to make a kit to run factory pushbuttons with a later non-pushbutton trans. Can't remember if such a kit is still available.

PS: pushbutton trannies are great. Learned how to drive with one. Have four of them right now - 56 Plymouth, 59 Dodge, 63 Valiant, and 64 Polara.
