Very nice Paul. Just curious, what differentiates an 'S' clutch and why?

Thanks,
Mike

Thicker foot on the pressure plate, combined with thinner clutch disc. Less rotating mass for engine

'67S/'68S clutch pressure plate had an alloy clamping plate with copper mating surface but used a std thickness clutch disc.

'69S used a similar pressure plate with an alloy clamping plate but with a steel mating surface & a unique thinner (approx 6.5mm) clutch disc.

That would be a 1967 911S pressure plate; due to copper facing.
My guess is that the 4 spring friction disc is 914/4 which I understand is functionally the same as a standard 911 disc. I always upgraded my 914`s to the 911 6 spring discs, and had no trouble. The 1969 911S friction disc is always 6 spring in my experience.
