Mines packed up, the poxy piece of shit


i have a spare gearbox from a DOHC 4x4 sierra

now from what i gather, they are both the same strength, same fitment etc etc, but i'm unsure if they are the same gear ratio's - i can live with the lower gears been closer together aslong as 4th and 5th are the same - i'm 99% sure that 4th is 1:1 on both boxes, but i'm unsure about 5th and the other cogs.


any advice please?
