If you can find a 3-series carrier, 3:27, 3:45 and 3:73 ratio are out here. But it will take a search for these ratio's new or used. And replacing gears's on a working rear even a 2:77 ratio a low priority in my opinion.

3:73 9-bolt gears will require a 3-series carrier, or they will be worthless with his 2:77 2-series carrier.

i'm not sure exactly what is in my 9 bolt it is a 87 TA, 350, 700R4, all wheel disk so actually i think it has a 3.27 i just want to get a higher gear to launch as hard as my friend he's got a 4.10 and it was the biggest jump out of all his mods

ps... 9bolt.com has a thing up that says in oct. they will have 4.10 gears but for $225 that seems way to high for my price range
