Got a 10 bolt 8.5 ring 30 spline Auburn posi unit for sale, my screw-up is your gain , I need a 28 spline !! The unit is used but in great condition, I drove the car it was in before it was pulled, they went to a 9in. rear-end. Asking 160.00 or may take offers or trades Like I said I need a 28 spline unit !!

Thanks Brad

 

Unless you have a 8.5" rear in your car, you need a 7.5" (not a 8.5') to go along with the 28 spline axles.

 

That is true if I were putting it in a car, it is going in my 87 Chevy 1/2 truck, which is 8.5, but thanks alot of people wouldnt say anything !!

 

No problem, wasn't sure what it was going in, so I thought I would mention it.
