I'm getting a new one fabbed this weekend by a guy who does driveline's for Busch/Winston Cup cars. It is for a '71 SWB 350/350.

All I has to do was measure from the transmission output shaft to the U-joint cup on the yoke, and run a string between those two points to measure the clearance through the hole on the crossmember (ride and drop). This is to insure that the driveshaft does not hit the crossmember when going over bumps, ect. Someone put a 3'' OD shaft in mine at one point and it did not have enough clearance through the crossmember hole...and got beat up. Very shaky, to say the least.

He is going to use the piece that goes into the trans...but everything else will be new (and balanced)...U-joints included. The new shaft will be 2.5'' OD but made of some kind of thicker walled steel that he uses in the race cars.

Total cost: $170 US.

A driveline shop may be the ticket you are looking for. Good luck!
