Trying to find consensus on whether or not lockers, limited slips, spools and mini-spools are interchangeable.
Im seeing spools for the 8.5 but nothing for the 8.625 specifically.

Do you mean 7.5 and 7.625? They basically interchange, watch the spline count.
8.5 is a different animal. Never heard of a 8.625

The 8.625" is usually referred to as 8.6"
At this Site they have good info on them, looks like the differentials do interchange, just have to match the spline count on the axles and also the differential bearings too.
8.625 was in trucks like 99 up I think

Looks like they interchange if you have the right axle spline count.
I did look into putting a 8.6 carrier in my 2nd gen camaro 8.5 to get the 30 spline axles, there's something about needing different bearings though.
Yes, pre-'99 was 8.5" ring gear. '99 and up 4.8 and 5.3 had 8.6(25)" ring gear while the 6.0 got 9.25?ring gear
