The shift shaft isn't broken and the splines on it are fine. The used shifter I got when I finished my build last September the splines gave way. Probably had to do with the guy I got it from had to large of a bolt in it and it was stripped out and wouldn't torque down on the shift shaft. I've already got a new shifter being delivered today from Jason and the proper bolt coming tomorrow or Saturday. I will keep this shifter along with my other one that's splines are shot as well and do what you guys recommended to them and keep them in my box as backups.
