Any of the 4 Ford transverse boxes will fit (with the appropriate flywheel/clutch/starter):

BC >95
IB5 95>
MTX75 92>
MT285 02-05

as will longitudinal ones with the correct bellhousing/mainshaft.

Not all are the same though. For example the MTX has versions with rod gearchange and 2 different cable changers. Also the casings differ depending on car/engine it was fitted to (different bolt bosses for mounts, V6 engine). Also the gearbox front/bellhousing needs to match for starter motor position, late (blacktop) Zetec gearboxes have the starter behind and above the block.

Depending on the age, the best/easiest source for cluster and FD ratios is the Ford TIS. Pre '98, probably a Haynes manual.
