Early A body 4 speed

Good question. I have wondered the same thing. I would think you could, but not too sure myself. I will have to keep an eye on this thread.

Well 30 years ago I did take an output shaft and I know it took a few other changes too from a later trans, but I made the trans into a later model driveshaft yoke style.

I can also tell you that the early trunion style is very strong and you can make it work too.
