If you use a later MTX with hydraulic release, then a 'blacktop' 2.0l flywheel could be used with a Focus RS AP Clutch, organic or paddle available.
What is the flywheel face/block height and setup height of the cable release MTX? There are many ways of swapping parts/adapting to get what you need that 'specialist' suppliers don't like to discuss. I'm running a Vauxhall C20LET with a solid flywheel and MT285 (Focus ST170 gearbox) on a standard zetec engine, but had to work it all out for myself.
A batch of the standard FRS AP clutch seem to be trickling out on Ebay at the moment going for less than £100 each !
