jack that bad boy up, and get the axle code off the axle, go to the parts store and buy a hanyes manual (if you dont have one) and it will tell you in there

[ridge_runner]

or just give me the axle code when you get it and ill tell ya what you got

[ridge_runner]

o and i cant believe i left this out but the axle code is stamped on the front of the right axle housing, you might have to clean it up a little bit to be able to read it

If you have a 9 bolt there should be some tags on the left and right side of the cover held on by one of the bolts.

a 9 bolt? do you mean 9 inch, but thats a ford rear. did they really make 9 bolts?

[Dober89]

yes a 9 bolt. It was in 87-90 Irocs only I think. It was a Borg Warner unit made in Austrailia. Mine came with aluminum disc brake calipers. It had a larger ring gear then the 10 bolt at the time. I think the 10 bolt was 7.50" and the 9 bolt was 7.75". It was the performance unit put in the Irocs.

my 90 rallysport has the 9 bolt borg warner rear end too.

so does my 89 IROC, but also, look in the glove box, for the three digit build code that is GU# the number being between 2-6 that post it here, and i can tell you what gear ratio you are running, much cleaner tht way.

[Dober89]

You mean the center console??? Everyone that gets in my car always wonders why theres no glove box.

[boots03]

It is GU6

[ridge_runner]

damn that code is not in the book, you sure its the right one??
