I may not be able to answer this and prob someone always knows better BUT - i am building a makeshift FRS mk1 for my daughter de tuned to 200bhp - everything else minimal like the T230 lightweight etc

Building up the engine and gear box i have gone for MTX75 I randomly purchased on facebook for £50 the guy said it was mk1 focus and i assumed it would be ok - WEIRD THING IS i have to use a standard mk1.5 shifter with unknown cables but similar to RS and i had to buy a Transit shifter tower also for the gear box - NOW I HAVE GEARS - i hope this info point u in right direction it s not an answer more me describing me effing up my projects lol but hopefully some info -

So to conclude the Transit MTX 75 shifter is similar or same as RS....OR same as Mondeo hence maybe i am using rs Cables.........
