rear axle identification

A quick trip through Randy’s Ring and Pinion catalog should shed some light.

I am guessing the gears are the same, but the side gears might be different to accommodate different splines on axles. Not sure I want to get that intimate in shuffling parts around without knowing that they are all going to fit, but the gears and yoke are really all I need. I will try Randy's and Rockauto to see if there are any particular differences. Any other sites I should search?
