Mi16x4 transferbox, prop shaft and rear diff are esentially the same as T16,
but they have a different ratio and the three must be used together.
gearbox is completely different but funnily enough they're both compatible
with either of the transferboxes, so you could leave yours!
however, you'll then need to swap the flywheel for the Mi16x4 one and get
a very stong 215mm clutch made, or keep the flywheel, modify the bellhousing
to accept the 235mm clutch and have a custom plate done.
btw, Mi16x4 gearbox/clutch is push type while T16 is pull type (like 306 GTI-6).
hope this helps
