Clutch disc diameter?

IDK what size clutch your 1971 Demon with a 198/A230 has,
but since the 198 is the smallest slanty available in '71,
I'd guess it has the smallest clutch;
But I'm just guessing, lol

Yes, it's logical :). But an optional 9 1/2" disc is mentioned in the FSM for the 198ci.
So, I suppose that it's impossible to determine the disc diameter without removing the transmission... :rolleyes:
