Just put a type 9 behind my crossflow 1600. Bloody easy really used standard 1600 bellhousing, clutch and release bearing, clutch cable, gearbox mount, just need longer speedo cable, cut top of tunnel and rotate by 180 degrees (moves hole @3 inches back)
I bought some blocks for the gearbox mount from the uk but they didnt fit so made my own.
Single piece prop i have a mk2 tina one fits fine.
I found it easy as i put the engine and box together then put the lot in the car.
There are better boxes than the type 9 but if you can get one at the right price you dont need many more bits.
