That's the one that Thunder sold me. I'll double check tomorrow to make sure it fits right. Only difference seems to be the size of the head.

Stock bolt is 7/16-20 x 2-1/4. Stock head size is 5/8".

Thanks. The only difference between those two is the bolt head size, one is 5/8ths and the other is 13/16, and about $2.

You know you never can get enough head.
I'd recommend the first one since mine didn't quite fit inside the stock hub.

The one with the 5/8ths head worked great. It was tight, must need a thinwall socket for the 13/16ths. I am so glad the tap cleaned out the crank.
