Ok, well i was wondering how big of a job it would be to put an '03 6 speed tanny which im not sure what kind of transmission its actually called, but anyways, yeh.. i have a 98 cobra with the stock 5 speed it came with.. and i wanna put 4.10's with a 6 speed? is that possible and if so how big of a job and also is that gear ratio and transmission a good combo? Especialy if i wanna supercharge soon?
