Just found a set, thanks guys.

 

ttt. Really need these. and keep in mind I'm looking for used ones because I can't pay new prices.

 

I've got several low milage main shafts but can't give them away. Let me know if you need one.

 

If those splines are almost stripped then I would take a look at the 5/6 cluster that rides there. I'm sure that one is also on it's way out. Call Jason at Texas Drivetrain Performance and he can sell you one that has been machined to tighten that cluster and keep it from vibrating and tearing that up again.
