if its got mt75 box then i believe the mondeo flywheel and clutch is useable, thermostat housing and water rail i think is available from retroford if im right, i think they also do mounts for the zetec too. sump may need changing to escort type?????? water pump and pulley may also require changing to escort/fiesta type. rwd exhaust manifolds are available too. if you have power steering then keep the mondeo pump too. engine management depends on what you want to run, but the mondeo engine loom/ecu/transponder would do fine.
