Australian Rearend???? Hi
I am looking at getting some parts from a guy wrecking a Firebird. It has the 1LE parts and he claims it also has the "bigger Australian" rearend. Is this reality, or is he bull-shitting me?
Thanks JA

The 9 bolt is stronger than the 10 bolt. I think they were only made for a few years on the third gens.

"The Borg Warner rear end is sometimes referred to as 'the Aussie rear end' or the 'rear end down under'. Why? Simple. The Borg Warner 9 bolt rear end was manufactured by the Holden division of GM of Australia. A few (so I'm told) aftermarket companies make gears for this rearend, but I was only able to locate one such company. This company is mentioned in the Sept. 1999 issue of GMHTP and is Reider ((734)-946-1330)) which manufactures a set of 3.73 gears for this differential. Be warned! If you have a 9 bolt with a carrier that came from the factory with 2.77 gears, you will need to replace the carrier as it will not accept gears lower than a 3 series. If your carrier is factory equipped with gears such as 3.08, 3.23, etc., then you are OK and the 3.73s will slide right in."

I am not 100% sure, but the 10 bolt rear from our cars can fit in a 3rd gen without a problem

after i blew the my 2.73 drum rear in my 89 i found a 3.45 9 bolt disc and slaped it in and it was a nice rear but the posi went on it and they are really expensive so i found a 3.73 posi disk 10 bolt(10 bolts came with disk also) and put that in
tests have shown that the 9 bolt 7.75 ring gear compared to the 7.5 gear in the 10 bolts actually to be just as strong if not stronger then the 8.5 10 bolts
the great thing about the 9 bolt is no c-clips...the axles are bolt in like 9"ers which is awsome
i wish i would ahve kept and fixed it
