My '57 3100 stepside had no trans in it when I got it last weekend...I know it was a 4-speed before the previous owner yanked it. What years of SM420's will work in a '57? I have a truck bud trying to sell me his SM420 out of a 66 rig. Will this fit in the '57? Also, I have no driveline. I was reading up on drivelines and seems that some got "torque tube" and some regular yoke? Anyway, Anyone got part numbers or pictures of a stock driveline? In particular a length to work off of would be great too.
Thanks-Dano
