the bell housing is different as well as the input shaft length.
it sounds like the op wants to put the zetec final drive in his mtx when he swaps to the 3L. This can be done but you need to know what design level input shaft you have in your mtx. My 2k mtx I purchased used happens to have the early level 2 part (iirc) input shaft that would require discontinued parts to change to the zetec final drive ratio. the new level input shaft, iirc, is easier to change to the zetec final drive ratio.
best to head over to fordcontour.org and sign up so you can ask question of Terry at HMS about your mtx and your options for upgrading it.
