Hey everyone, i know this isnt the correct place to ask a tech question but its the best place to get a response in any amount of time. So here goes...I have a friend that offered to help me change the gears in my 03 gt to 3.73s. I bought the gears and a bearing kit but also needed to know what else do i need to buy?? How much of what fluids etc etc! Thanks everyone any responses are greatly appreciated!
