Does anyone know if there is a 3.23 posi setup for a 72 455/auto with a 10 bolt case?

Or must it be a 12 bolt case?

Your 72 should have a 10 bolt corporate rear end with bolt in axles. Parts are readily available from any supplier, summit, Jegs, etc. You can also have your rear end shop supply the parts.

Just search for parts for 8.5" 28 spline rear.
