new strange 9-bolt 3.70 gears ring and pinion

Has anyone else seen these? Correct me if I'm wrong but this should fit our Borg Warner 9-bolts. I didn't know any manufacturers were making new gear sets for the 9-bolts. It's one helluva chunk of change for some gears, but maybe that'll drop with time.

right those need the 3-series carrier. I didn't know the 2-series was the most common... What did those rears come in? AFAIK TPI350s and TPI305 autos had the 3.27s and the G92 TPI305s manuals had 3.45s. Was the 2-series used in v6s or TBI cars?

Yes those fit the 9-bolt. Why would that happen?
All that will REALLY happen is that all the people who talk out of one side of their mouth about twin turbo this and 500 HP that, and p*** and moan non-stop out of the other all the time about how much parts cost, and don't buy anything at all (except maybe a $50 Summit cam) but rather content themselves with uselessly hacking for free on their emissions systems and wiring and A/C and end up devaluing their cars to trailer-park POSs, will fail to buy them at ANY price; and since higher volume drives the price lower, and lower volume drives the price higher, the price will continue to go up and they will eventually be discontinued by the mfr for lack of sales. Meanwhile, the cars will get torn up and wrecked and junked, and the "installed base" will shrink even further, and the whole economy of scale thing will continue to work its magic on the price. There's no downward pressure on the price, it's ALL upward.
And notice, those only fit the 3 series 9-bolt rears; 3.27 and up. ALOT more people who might ACTUALLY be willing to spend money on their cars, have 2 series rears (2.77 mostly), which those won't work in. 3 series 9 bolt stuff is already hard enough to get hold of.
All in all, I don't see those as making much of a splash in the marketplace; hardly even a ripple, really. Kind of unfortunate but that's the reality as I see it.

2:77 2-series stamdard 350 TPI
3:27 3-series extra cost option 350 TPI
3:45 3-series G92 option 5-sp 305 TPI
None were offered with V6, LG4 Carb/LO3 TBI 305s/
A few 3:73 on very early 5-sp cars and not worth looking for.
Thats it for the 9-bolts and they all had limited slip. Last factory installation was on the 1989 Camaro/Firebirds.

forgive me for taking all this personally if this isn't directed toward me, but where the hell did all this come from?
Now I know why I questioned whether or not to even post this... Thanks for all the friendly help and advice.
----------
Most common and only Factory 9-bolt ratios were:
2:77 2-series stamdard 350 TPI
3:27 3-series extra cost option 350 TPI
3:45 3-series G92 option 5-sp 305 TPI
None were offered with V6, LG4 Carb/LO3 TBI 305s/
A few 3:73 on very early 5-sp cars and not worth looking for.

gotta agree with sofakingdom here, rarely do people in the car world actually do what they talk about doing. When it comes time to cough up the cash, it's mostly pipe dreams. I've noticed it more with car people than anything else, you don't see people get landscaping estimates, or roof estimates when there's a hole in the roof or no grass and then not do through with it.
100s of people complain that they want the jongbloed hood, or 5" tall rear spoiler, then they're made and bam....not even 100 orders total for the guys who step up to the plate.

Alot of history.... Nothing personal about YOU. Just alot of reading people talking the big talk about what they're "planning", and then the brick wall when they find out that it actually costs money. I've had about 35 years worth of it from people whose "plans" had no spine behind them.
I do change my plans frequently though, it all depends on what deals I come across. If I were to find an LS1/T56 setup for my car, I'd go buy it. Then I'd find a car to drive around for work so I could take my car off the road and do the swap. I'd save up for a k-member and A-arms and coilovers and keep a lookout for good deals. And everything that I've amassed for my Gen1 SBC T56 swap would be up for sale. I've done my share of buying on these classifieds, not just window shopping.
Anyways, thanks for clarifying, no hard feelings.
