Help please, which diff will directly bolt in? Hi guys, the broken diff saga continues...
I've given up on repairing the internals as after being told by my mechanic (admittedly NOT an fbody expert) that I need to get 10 new replacement cogs/gears, I can't find any packs with more than 6.
Also, there are a few diffs on ebay that are not too expensive, I just would like one of you experienced guys to confirm that they will fit as there are some specs listed that I still don't fully understand.
* I know that I would be better off getting a 12bolt or a ford 9" but the truth is I just can't afford one at the moment and I need my car back on the road so that I can get back to work. *
This is my existing (broken) diff: https://ls1tech.com/forums/gears-axl...ranny-too.html
Here are a few that I have seen on ebay. None of these are these are the exact one that I am removing from mine (torsen) so can anybody confirm if they are a good or a bad idea:
1 Auburn pro differential:

'GM 10 bolt, 28spline ,7 1/2 & 7 5/8....3:08 & down pn# 542047' 3:08 & down, does that mean my stock gears are too big a ration for this diff?
2 Eaton Locker Posi

3 3.42 POSI:

Thanks for reading guys, I know that this is probably a stupidly obvious question for some people but I am still new to this game (and loving every minute of it...except when my diff went boom when I hooked up on launch lol).
Any help or advice would be much appreciated.

'96 trans am, should fit my '98 formula no problems, might need to do something with the trac control but the FAQ's say it's do-able. I'm buying it...if only it wasn't in Essex!

Here's the deal, all camaro/firbird ten bolt housings are exactly the same from anywhere in the late 80s to the end of production. Exceptions are 3rd gens had 26 spline axles, 4th gens had 28 splines. So since i dont know what year your car is you will have to determine what will work with your axles. Secondly important for you is carrier (posi unit),2 series is for 3.08 and lower which is 2.73 for our cars. Did your car come with 2.73s? or did it come with 3.23s? 3.23s would be a 3 series posi/carrier. So lets say you have a 3.23 4th gen, you would need 3 series 28 spline axle version of any posi and it will fit. Doesnt matter if the housing is from a 6 cylinder or 8 the casing from the two is the same, only difference is whether they are 3 channel or 4 channel pertaining to traction control which determines where the sensors are located.

I've bought a 2/series carrier with 3.08 gears to keep shipping costs down. A slight upgrade from my 2.73s, I'm not holdin my breath to notice any difference, just want to get back on the road.
Matt: I'm in Wirral, right next to Liverpool. Would of had to hire a van or a courier as he wanted pick up only for that axle.
