i looked at my rear end the other day, just curious..
anyways, 8.8 is stamped on the bottom right side of the differential
does that mean it's an 8.8 rear end (it is a 3.8 LX), or do they all have 8.8 stamped on them?

Yep, the 8.8" was an option on the 3.8L's. My 94 3.8L LX came with the 8.8".

The certification label does have axle type (AXLE) and brake type (BRK) on it. The axle code tells you the ratio and whether its conventional or trak-loc, but not the size.

AXLE
1997
5 = conventional 3.27
E = trak-loc 3.27

BRK 1997
1 = 4 wheel disc
4 = 4 wheel disc w/ ABS
A = front disc rear drum

But do you really need to look up codes to tell if you have ABS or not?

The 8.8 housing is more squared off than the 7.5 housing if you look at it from the rear. I just bought a rust free 95 LX 3.8L which has 4wheel disc/abs and it has the 8.8 , My 96' with 4wheel disc/abs came with a 7.5 from the factory.

My 94 3.8 I used to own had an 8.8 with a 3L08.That thing did better donuts than my PI car!

I went to a junk yard today in wrightstown today and looked at 7 mn12's.
no track-loc's and only one had a 7.5.
It was actually the first 7.5 I've seen in person.
