Same as above basicly. The Fiesta RST gearbox has nothing fance or uprated in it, so any 80-95 FWD 5-speed gearbox will be fine, for except the MTX-75 which was usded in the 130ps zetecs and 150ps RS2000. However, you can take this opportunity and install a LSD equipped box as they seem to cost next to nothing in England.
