3:73 R&P for D35 non-c needed

Was looking into the vibrations from the rear end today and changed axle shafts but still have the vibes. I guess my next thing to change is the gears. Anyone have a 3:73 set laying around? Also figure I should put in a limited slip.

I just pulled the ring and pinion but it doesnt have a limited slip. It also comes with the carrier make an offer it is just taking up room.
