I need to figure out which clutch/pressure plate I have on my 5.0/T5 combo (that is in a vintage car) to eliminate some causes of a very stiff pedal. I want to know if it's the HD clutch.. I seem to remember a FRPP part number. Is there any way to view it? It seems that FRPP stamps the number on the outside of the pressure plate. Is this viewable from the release arm hole?
