The 1.8Diesel sierra box has the shorter input shaft. It can be used but you need to make a spacer to move the flywheel about 3/4" closer to the box.
If you want to use a Type 9 then you need a V6 box or one from a 2.3 diesel sierra. Then either the cast steel capri(2.8)/sierra (xr4I) bellhousing or the alloy one from the XR4x4 2.8. You will also need the 2.8 flywheel.
You will need a type 9 sierra propshaft if you dont have one.

A type 9 is fine if you dont give it too much abuse. MT75 is more up to the job though.
