Default Grinding at WOT

I get a pretty bad grinding at WOT. Car has either 373s or 343s in it, I cant tell but its not the stock gear.

Rear is whining and the posi is shot, so I know it needs a rebuild but dont know if the grinding is coming from the rear or transmission. Transmission shifts fine but I can feel the vibrations in the console with my arm.

Anybody have this before. I think there may be too much slack in the ring and pinion, I can turn the driveshaft about a 1/8-1/4 of an inch before the pinion hits the ring.
