0.030" runout on the tail end of the drive shaft! The car has had a vibration since I bought it 6 years ago but it was only noticeable at 100+MPH so I kept putting off finding the source. The worst part is I paid a shop a lot of money to shorten and rebalance this shaft when I installed the T56 Magnum a couple years ago but obviously they botched the job or just cut and welded it without checking the finished product.
Regardless, this shaft is now scrap. Any recommendations for a replacement? I'm kind of leaning towards a carbon fiber shaft from PST since I need a custom length anyways.
