Hey guys,
Go here, http://www.transmissioncenter.net/sp...n_______va.htm
They have the calculator for the gears both drive & driven.
A reliable supplier of gears and You can also order custom ratio adapters from them.

 

IIRC those are the same people that I talked to when I ordered mine. They were really nice and nailed it spot on when I told them the transmission, tire size and rear gear.

 

so i'm pretty confident that i figured this one out. Thanks to Camaro 69.
I'm getting a 8 tooth Drive Gear and a 24 tooth Driven gear. so with 4.10 gears and 225 70 15 tires i should be all set. anyone want to check my math on this one?
