Jon,
The larger (8") clutch plate & flywheel is what was used on the
series 3, 1600cc engine. The 7.5" & smaller/lighter flywheel is from a
1725 series V. both will work okay except there may be a problem of
different clutch release bearing assemblies. Question, could you measure
the diameter of the carbon bearing? To use the 7.5 clutch, one needs a
"tall" pedestal and "small" carbon bearing. For the series 3 clutch, one
needs the "tall" pedestal and "large" carbon bearing (2.5"dia). I have
chopped flywheels for both 1600 (less 4.5 lbs, same weight as the Lemans
flywheel)& 1725 (less 3 lbs) and they come with new ring gears is needed.
