serial numbers. ask a chevy guy but pretty sure serial numbers will have that info. or just pop the cover and count.

and i think it will be stamped on the ring gear aswell.
my aswell pop the cover now, its ot like you can do the swap with it on there.

they are stamped on the gears you just have to do a silly dividing equation to figure it out

A 90 should have the axle info on the build sheet or the info tag in the glove box.
