im not sure mate

they are different Boxes.

derv =MTX75 as said

BUT IF the Starter motor is on the same side of the engine
then it should fit Straight on.
(some escorts had starter on front, some on back)

Beware though mate

MTX75 uses a Bigger Flywheel and clutch too
So if you are going for the change, then you will need the
Flywheel and Clutch from the IB5 car too
(along with gear linkages too as MTX uses lift-up reverse)
