I also have got the same Fiat-engined car. No workshop manual, but in the "Morgan Owners Handbook" it says:
"Clutch: Diaphragm Spring Mechanical Cable Operation Single Dry Plate
Clutch Release Arm Free Movement: 1/10" (2.54mm)"
if that is of any help to the mechanic.
(I have uploaded the entire handbook for the +4, 1986 Fiat-engined car to:
