GEAR HELP!?!?!? 2.73 to 3.73???

[Purple94z28]

So my rear end is at a local shop to put my 3.73 gears in and he got it all put together and he says there is way to much backlash? He says i need a diff rear end or carrier to fit the gears? Also i looked something up online about a spacer that will make the gear fit in my 2.73 rear end? Im just looking for an answer? Thanks in advance for any help.

Thanks,
Nick

so you have a series 2 carrier, did you get 3.73s for the series 2 or 3?

i got three series gear i just found out and a guy localy has a 3 series carrier for a gm 10 bolt and he wants 90 bucks for it and it might need new carrier bearing. Is that a bad deal and will it just drop in tho?

I would pay 75-100 for a zexel-torsen and 50-75 for a regular LSD unit

i think so, theres gotta be a rear end shop that whould know. if it does work i'd get it, bearing shouldnt cost more than 30

I ended up just getting a spacer for my 3 series gears to fit on the 2 series carrier but im bummed because there is a good chance the spacer bolts will sheer

I had a spacer in my '86 and never had a problem. Got a 2 series posi for $50 and payed $30ish for the spacer.
