Hi, Just wondering if somebody could give me some advice on building a hybrid gearbox to fit the YB cosworth engine RWD, i have the mt75 2.0 rwd box and know the cossie flywheel fouls it and i need a mt75 4x4, so all im wanting to know is what exactly do i need to modify it to fit.. Propshaft mod? clutch mod? gearbox shaft mod etc? could somebody tell me everything i need. Thanks in advance folks!
