WTB: Driveshaft

[ammrpm]

I need a new driveshaft for my 93 ZR-1. I was having a driveline vibration issue with my car. I took the driveshaft out to have the balance checked. Apparently the driveshaft has a very large runout issue near the slip yoke.

I am looking for a good used driveshaft or a source for a new aluminum driveshaft.

Thanks for your help!
