The UK P.I. TR5 and 6s had outputs of 150 b.h.p., so you can fit a
clutch from a TR (to keep it in the family so to speak) They are
diaphragm clutches and whilst you do need to redrill and tap the
flywheel (or fit a TR4A flywheel which has a diaphragm cluth), they are
virtually a bolt on job. The release bearing is different and the
gearbox has a small modification on it. I fitted one on my TR4 and it
gives no trouble at all (that's asking for trouble I suppose !!) If
the manual is pre TR4A/5 then that would explain why the above was not
suggested.
