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
