put in 8 3/4, now have vibration

Thanks for the additional input fellas. Unfortunately I've been really sick the past few days and unable to get back under and measure or take more pics.

From everything I've read, I think its time to bite the bullet and take my driveshaft into the shop again... see what they can do with it. My best estimate is the slip is about 6 to 6.5" long, so maybe they can put a longer one on it. If not, I guess I'll have to pay for a new driveshaft and eat some crow. Won't be the first time, and probly not the last either...
:oops:

PS - Badsport: my tranny is a833 with OD
