Thanks, I do remember that thread but I thought someone had said before that it would actually break or snap in half. Maybe I misunderstood what I read, it was several years ago. I have two sets of the slip shaft with the ball and socket and even the spring NOS. If this is the only problem, I am covered. My driveshaft is pitted really deep so I am going to piece another one together out of better parts. I have a nice front section from a 4 speed car and a nice rear section from an automatic car and then the NOS parts. I was just concerned that if a shaft could brake on me I would just take it to a shop and get the ends welded to a new shaft.
