Glad to see some one is paying attention. I certainly wasn't...

Yeah,it spins free with very little resistance but you can feel the internal splines rubbing/clicking on each other.

Tim- I have no explanation man.

Chevrolet all the way- I didn't check the sprag. After seeing all the debris from the splines I realized it needs to go back to Chuck (FLT).

I talked to Chuck today and he said he hasn't seen this before. He has 80's behind a lot more power than I have. It's headed his way tomorrow. It's getting a stock one again but he said sometime soon a billet one will be made. It's not out yet but I think I really shouldn't need it.
