I recently purchased a 2002 Camaro, 5.7, A4. What is the rearend that is in it or how can I tell without opening it up?

IF its a stock gm 10 bolt, the POS will have 3.23 gear ratio for an A4 car

Don't some A4s have 2.73s? and I would assume by looking if it has 10 bolts on the cover lol

Isn't there a 7.5", 8.2" and an 8.5" 10 bolt? By the RPO, I know I have the 3.23, but not sure what size ring gear. Is there something in the RPO that tells or a marking on the housing?

To my knowledge, all the stock rear ends for these cars were 7.5"

2002 Z28 A4
from/off the factory production line
set-up for 3 channel ABS(standard) or 4 channel ABS & Traction Control(optional)
2.73:1 gears(GU2)-standard-came with steel driveshaft
3.23:1 gears(GU5)-optional extra cost as performance rearend-came wth aluminum driveshaft

came with a 7.625 gearset
7.5 is the same as 7.625.
a 7.625 rearend has a 7.625 OD ring gear mounted on a 7.5 carrier.
a 7.5 rearend has a 7.5 OD ring gear mounted on a 7.5 carrier.
rearend parts are the same: bearings,seals,shims,etc.

Thank you!!!!!!!!!!!! I do have the GU5 option I saw it on the RPO. It had several different options than normal stock because my Camaro is a B4C, the Police Interceptor model.
