3.23 was the optional gear in the automatic V8 Camaros 1994-2002.
I've heard stock 8.5 1984-1987 Buick/Olds axles work for that swap. Guess I should get off my butt, pull some parts and go verify. :yell:oh no, I'm taking the carrier and rear brakes off and throwing into the camino. It's a 7.5 28 spline so i'll have to hunt down some new axles.
