I have a vibration (don't all the F bodies?) and am going to rotate my driveshaft as a free last resort before spending cash. Do I rotate the front and back or just the rear at the bolts? Hope this makes sense and thanks in advance for help. Also, how do I check the yoke to see if this is the cause? (I had a clutch put on last year and the vibe started afterwards).

Unbolt the driveshaft and rotate in 180 deg in the back the transmission wont matter the idea is that there is almost always a high side of run out in the yoke and a heavy side of balance with the driveshaft you want these to bew opposite each other or as far away as possible.As far as yoke run out goes there are tool avalible that bolt in the U joint saddles and you use a dial indicator and it will tell you run out looks like a big ball bearing with u joint caps there very expensive mine was over 700 bucks...
