don't know about the 33 gearbox fitting into a 32, might need a different x member. anyway a friend and i did my conversion. it would be abit harder because mine is 4WD and the box is about 2x heavier.
parts - clutch pedal, brake pedal
clutch master and slave cylinders
gearbox, clutch, flywheel ( need the manual flywheel bolts aswell )
manual spiggot bearing
manual x member
i think the tail shaft will fit ( mine did )
manual loom off gearbox
gearstick, console part that goes around the gear bit
you'll also need to cut a hole into the floor for the gearstick to come through.
i think thats about it.
i would just stick the 32 box in then find out how much the 33 box costs to fit cos the 33 box costs alot more than the 32 one.
