Transmission or rear diff. problem

Hello,

I have a 70 Duster 340 4spd. I seem to be having a problem with either the A833 trans adjustement or the rear diff. When I launch the engine revs up and it sounds like the wheels are spinning, but they are not. It's almost like traction control. The clutch is fairly new so I am not sure if it's slipping beacasue something is out of adjustment since I rebuilt the Zbar assy?? Or could it be the sure-grip unit clutches slipping and the unit needs rebuilt?

Also, the rear end howls a lot due to some pitting on the ring gear. Does anyone know any Mopar rear diff. guys in the Atlanta area that could rebuilt the 489 case for me?

Thanks,
