I have a 3.08 non posi rear end in my garage that my dad gave me. Are the gears and axles the same in non posi rear ends? If so I'll only buy new seals, bearings, gear set and a posi and use the parts from the non posi unit to build one.

If you're wanting to do gears anyway, I would build the other axle and then when the time comes just swap the whole thing as one unit. As stated above some end play is normal. Without inspecting the actual ends of the axle inside the differential you can't really judge.

So long the non-posi is an 8.5 in rear end from an impala all the major pieces are identical. You may want to double check with a search about 9c1 axle widths vs impalas I know there are some differences.

'95 B4U LT1/T56 in Purple Pearl. 24x 355 with I believe most of the bolt-ons.
'63 C10 LT1/4L60E from B-Body. Rides like a Cadillac thanks to air bags.
'06 GTO LS2/T56 Torrid Red with CAI and Borla Cat-back thanks to the lady who rear ended me.
Still in Wichita.

IIRC, a 9C1/Caprice 8.5 10 bolt rear end is 1" narrower than the "SS" rear end

The diff can interchange but I assume the axles are not the same length
