need help identifying some gears

[Blue_71]

yeah those gears are pretty aint they im guessing thats from the 2 pinion bearings letting it jump around (what ive heard anyway)

what do i need to search for, just a detriot locker for a d70?

strength wise, how does that rear compare to a good working HO52?

i was hoping for something fun (aka 2 wheel rooster tails) without having to spend more money, but if i have to spend i like to hear cheap

it'll probably be a while before i put it in, the trans guy at work quoted me $250 to rebuild it. plus ill want to redo all the brakes first.
