I really don't remember I've got all kinds in the shop from past projects I just started grabbing pieces untill one worked. A friend of mine showed me this trick years ago and when he slammed my axle down on the concrete I almost lost it until I looked at the shaft and it didn't have a scratch. <img src="/forums/images/graemlins/lol.gif" alt="" /> I've heard people say they spent $200 per axle but I don't know if they pulled them or supplied the bearing or what but mine cost $50 per axle out the door. Good luck.
