Car is refendered

I finally have my car back with a newly painted old fender. Now its back to diagnosing some of the problems. My car has always had some clunking and vibrating issues in the power train. Whenever I go from drive to reverse or vice versa it thumps pretty hard. I pulled my slip yoke and it has a bit of play in it. Could this be my problem? I've already installed new u-joints but still have this issue.

I also have vibrations when I get going above 60 and either accelerate or decelerate. I figured this was an issue with my ball joints, but have been told otherwise. Any thoughts?

Hows is the transmission mount?

Whoever did the exhaust on mine, ran the driver side pipe a little too close to the drive shaft, and my yoke was beating it up right at the rear of the muffler. It only happened under heavy torque or on a bump.

How much slack is there between the pinion and ring gear? put it in neutral, jack up the rear, and check it
