your fitting it in a fiesta??
trim the fucking sump then LOL!!!
theres different years of mondeo zetec gearboxes,
silver top and early black top use manual speedo drive, later blacktop mk2 mondeo use the focus style gearbox (1.8 and 2.0 in mondeo are visualy and physicaly indetical) with rear mounted starter motor etc etc
the later ones can be identified by the very large rear diff housing and small 3 pin hall effect speed sensor above the o/s driveshaft
focus 2.0 gearbox has cracking ratios anyway, and the RS mk1 has an LSD
hopefully a bit of a better insight for you
