Long tailshaft 727?

Rob said

Thanks, I was wondering about the yoke assembly. I'm also swapping out the rearend for an 8 3/4. I didn't know the long shaft 727 was for cars, thought it was the other way around. I don't know if I can find the right driveshaft but getting the one I have shortened isn't a problem. Not sure about the yoke assembly though, can that be swapped out too or is it too big to fit into the current driveshaft?

Finding a driveshaft for your car shouldn't be any problem as they used 727's in A-bodies. But if you don't find one getting your shortened is a good option. In fact it might be the best way to go cause so many older/used driveshaft assy's can be out of balance. The yoke will directly interchange as long as the U-joint size is the same. I believe all A-bodies used the 7260 U-joint which is super common. Even if one end is the larger 7290 U-joint you can easily connect them with a conversion U-joint (7260 one direction and 7290 the other).
