My suggestion is ck the local Olds & Buick A-body guys that restore Cutlasses & buy partscars. The A9 axle bearing version housing with the square lugs are out there. Nearly a million were built of the most common style '71-72 housing (with the square lugs).

2 out 3 times, the factory gear ratio will be 2.73. If the ring & pinion are in nice shape, much easier to install a posi unit/recreating same backlash, than properly installing another gear set.
