Since I broke my drive shaft last Sunday I've been looking at getting another made for spare and found a good shop here in San Antonio. What do you know they have a pretty good web site.

Bunch of good guys working there and they have a nice clean shop in case you're wondering.

Thanks for that link. I have been wanting to get a real beefed up rear drive shaft. And I pass through San Antonio quite a bit. Will have to stop by and talk to these guys. Have you got your shaft yet? Is it pretty heavy duty?

Actually I just bought some parts form these guys, but I'm gonna get a spare shaft made in the near future.

I just had a shaft made by High Angle Driveline's.Excellent craftsmanship work great,will handle 1000hp and run at a constant 32 degree angle.Has a 1350 cv joint and 1350 u-joint at the diff end.
