The T50 is a Toyota gearbox dude, not a Ford. The reason why it matches perfectly is because it's the exact same gearbox used in the AE86, which used the 4AGE engine. T50s also came out in T-series Celicas, and are extremely common to use in Clubmans with A-series engines (one of my uni lecturers has a silvertop 4AGE 20V and T50 in his clubman) Woops I meant to write Toyota. Suppose that what I get for reading reviews of the XR5 just before I post :P Thanks for all the help. I’ve researched it a bit more and it although an adapter plate could be fashioned the gearbox itself isn’t the strongest to use. The bulletproof Supra box seems to be the recommend choice.
