escort is cable operated, this wont make a difference. the only thing with regards to changing the clutch youd have to check is if the clutch cover plate is compatible with the release bearing. if using a mk4/5 fiesta diesel clutch (assuming it fits the zetec flywheel) then there should be no issues with the release bearing. I cant find my old application book so cant say for defo if diesel one will fit. you may have to mix and match using a s2 plate with a different cover possibly. i normally use a s2 turbo clutch or mk6 escort 1.6/1.8 which is same.
