Ten bolt rear end out of a 1971 cutlass S: $125.00 plus shipping

Twelve bolt rear end out of a 1970 F85: $175.00 plus shipping.

I can put them on a pallet and deliver them to Fastenal for shipping.

Knowing what year and what gear ratio might be helpful information.

350 TurBRO. My 10 bolt was open and they bought a posi unit from west coast differentials and put it in my rear axle. SWEEEET! If your unit is 10 bolt and you upgraded to the 12 bolt from Olds442redberet and then got the posi unit (if available) you would have a stronger unit.

Yea, just wishing here too:
