I Need help finding drive clutch parts and for my 1955 - 15 A.  Disc and Pressure plate. Dos anyone know what the thickness and type of material they used on the original disck plate.  Mine is still good I just think it needs built back up to work.  Pressure plate seems good.  I had both that and flywheel resurfaced last time.  Just don't have much material on clutch disc left and I believe that is the problem. .           

Hi,
I do not recall the thickness of the clutch linings as it is some 50 years since working on these,
BUT, I do know they were a Velvet Touch lining.
I believe these days that people may be fitting their VT Clutch Buttons to the old discs.
The scans below saved from here a while back should get you a contact there.
Cheers,
Eddie B.
