Couple of questions ...

If you don't mind buying a new drive shaft, any good shop, like Denny's, can give the procedure to get the measurements they need to build you a new shaft without having the trans slip yoke in hand for measuring. And the new shaft will have all new parts.

Yeah, there are a few around here that can do that. My main concern is budget. It's my son's car and we spent a bunch of money on trying to revive the /6 that was in it. Gave up on it, one thing led to another etc.
