New, impossible. The only ratio available is 3.70's, and they cost over $400. Used, you'll be lucky to find them, but they're out there. You'll have to search the classifieds and junkyards.

OK, one more time, that is not a correct statement. I have 3.73's (not 3.70) in my car. Ratios to 4.11 will be available (also new series 3 carriers and other 9 bolt goodies) if i can ever get things finalized.

Miles, I know.
But I meant RIGHT NOW from current aftermarket manufacturers in the United States. They only sell 3.70 ratios.

Precision Gear sells the cheapest and most complete overhaul kit. All Timken Bearings. I paid 99.00 2 years ago. It may have gone up a few bucks since then. New Timken axle bearings cost me about 12 bucks each @ auto zone. If you have a 2.77 carrier you'll need to get one from a G92 car. I bought a bad posi carrier from a 3.27 car for cheap. The guts are identical, so if your posi is good just swap the guts from yours into the bad one. You can even check the tech articles for Karl Hunter's tip on 9 bolt posi's. Good Luck! Hope this helps.
