Retro Ford (01536 747978) do a Concentric Release Bearing kit which comes with the boss, bearing, replacement oil seal, bolts etc and a master cylinder for £249.50 inc vat.


Although it was originally designed for MkI&II Escorts etc there is no reason it wont go on a Cossie.

You will need to make up the pipes from master cylinder to slave cylinder, and a remote bleed pipe and then adapt the rod from the master cylinder onto the clutch pedal

Other than that.. should be ok.
