WOULD LIKE TO HAVE A 3:73 GEAR.
I.D.#4:10 DSTA-KNB 603584-5

 

Is it 4 wheel drive or 2. And what seem to be the problem with it?

 

IT'S 2 WHEEL DRIVE & SNAPPED THE RING & PINION GEAR
NEED COMPLETE REAREND
BROKE SHAFT IN FRONT PART OF HOUSING

 

As long as the housing is good you can have new gear's put in this might be cheaper.And scince it is 2 wheel drive you might be able to upgrade the gear's. Or get a complete rear from the junk yard.
