so if an mtx-75 came with the mondeo 2.0 duratec engine (same as what's in my car) but I have an ib5

If I want to put a mtx-75 in my car i.e focus rs gearbox will I need the bell housing off a mondeo mk3 gearbox fit on the focus rs gearbox and this would fit?

Or am I best fitting the inards and diff off the focus rs gearbox to the mondeo mk3 item? Can you even do that?

I know i'll need driveshafts aswell and please bear in mind that the duratec unlike a zetec takes a reading off the gearbox for speed, I think the zetec takes it off the hub?

Sorry for 1 million questions but I need help as my gearbox aint gonna like my new power
