I have been a member here for awhile but have never been inclined to post. I hope this is not old news. If it is, sorry.
I was at a tech seminar with a rep from Eaton/ Detroit Locker this morning and we were told that Eaton will have a posi unit available for the 3rd gen F-Body and new GTO crowd using the Borg Warner 9Bolt, by the end of the year.
There are many more F-Bodys produced that came with 9Bolts than GTOs that use the other type.
One of the reasons we were told this is that there is a rather large need for these units in Europe and Australia. They were used in Vauxalls(spelling) and of course Holdens.
I work in the performance aftermarket industry and have been told by vendors, of new products that were on the horizon but were never produced, I am getting good at telling who is full of %$& and who is not.
I am pretty confident that these units will be available and who better to do it than Eaton.

Stupid question: Is this just the POSI, or gears and POSI? Or are they just going to sell a whole 9 bolt rear?

I noticed my RH axle seal leaking on my 9-bolt. so I thought it'd be a good idea to replace the seals, both sides. I went to the NAPA store, they only had the RH seal (luckily), but no LH seal, no diff cover gasket. not even in the warehouse, can't even be ordered or brought in. not obtainable, also not available from CSK Parts America. I'd be happy if the little parts like this were READILY available. to add insult to injury, the RH seal was $20. by comparison, the seal for the 7-5/8 diff is only $3. gheez.
I'll have to try the GM dealer parts department. I wonder why there're separate part numbers for the RH and LH axle seal, compared to other run-of-the-mill axle seals.
several of the gear resellers have the overhaul kit for the 9-bolt, but you're talking $150 for the kit-n-kaboodle. all I need is the seals and diff cover gasket. I think I can get by without pulling the diff cover off, though. oh well.
I went down to my local GM dealer and bought 2 9 bolt differential cover gaskets about 4 months ago. They were $12.99 a piece I believe, was only going to buy 1, but hey, they had 2, I bought 2! GM still sells these, they cant be that hard to get a hold of.
You can get many different ratio gears for the Borg Warner 9 bolt from a company called Motospecs in Australia. I just bought 3:45 ratio gears from them. It was very pricey compared to buying from a place like Summit. The gears were over $300 and shipping was almost $150.

I called Eaton Torque Division today and the rep I spoke to said they had no plans to develop a carrier for the Borg Warner 9 bolt. He told me the market was too small and it was not worth the development costs to do it. Are we sure it was Eaton and not another company that was going to make the new carrier?

Ive checked the site out, and cant find anywere were there are gears or any diff parts for that matter you got a link perhaps? 450 for gears aint to bad I would so go for that If i could finally get some for he almighty 9-bolt
I'm so glad I bought those 4.10's for my 9bolt when I did!!! http://www.diffsolutions.com/ doesn't seem to be around anymore and he was about the only place that had other gearsets besides 3.70....I now have a 3.45 set and 4.10's...
