At stonely i spoke to Richard at GBS and he said it is now possible to mate the MT75 to the 2.0 duratec you will need the bellhousing case from the 2.3 LPG duratec transit new model.
Checked this with a bod at work and he says it will fit but not cheap but will work.
Once i have sourced a new 2.0 duratec i post on here and let you all now the out come

i have reciently bought a mt75 transit box, was told 91-2002. if you need any dimations etc, then let me know and i will get a pictured template posted up?

Im told that its only the gear box from the 2010 2.3 duratec LPG transits only?

Yeh it wont be the 1990 > as that pre dates the zetec. Thats end of cvh time period It would be cheaper to get a MCT mt75 from a morgan than 2010 ford trani box and a mtz5 and start making one from the two. Maybe an option in years to come.
