Should be a 4.10 rear (3500rpm @ 70mph on 205/50/15 tires).. I wheel hopped hard a few years ago at the drag strip and ever since it's had a whine to it... new tranny plus race tires and hard take off apparently killed it. :(
No 3.90 for me, I'm ok with the 4.10 setup. Wasn't sure if it was as
simple as just comparing exteriors on the cases, so I'll look at the bone
stock 92 POS I have and see how they compare but I'm 99% sure I have the 7"
based on the 4.10 setup.

Re: Fuel pump won't turn off
& rear end damage questions
If you have 4:10 gears, you have the 7", not the 6" (1.6l). Not sure on
how to check the health of the torsen (assuming you have one), but this may
be an opportunity to move to the 3.90 ring & pinion if you want.
If you have in fact disintegrated a 7" (1.8l) rear, your the first I think
I've heard of at least on a relatively low HP turbo car. Wally, you must
be hard on them. No too many flubbed heal/toes at the track have there :-)
?
The casing on the 1.8l diff, is physically larger in every dimension than
the 1.6l, but I can't remember if there are any distinguising charateristic
other than if you have one piece axles, then it's a 1.8l (96+)

Subject: Fuel pump won't turn off & rear end damage questions
So, repalced the transmission (2nd gear sheered 3 teeth again).. all was
good for 30 miles, then the rear end disintegrated. Leaking fluid out of
the case, makes ungodly noises. Questions:
1 - how do I tell a 7" from the 8"? I assume the car has the bigger rear,
but need to confirm.
2 - Anyone have 4.10 gears (ring and pinion) for sale?
3 - How can I tell if the torsen was damaged? Visual inspection or
functional test or both?
Secondary issue, after the tranny swap and prior to rear-explosion, the
fuel pump would not turn off after prime. Would continue running. Any
ideas on what might have cuased this? Ran fine otherwise...
Thanks,
Wally
