Correct size clutch for a 390?
Thanks - I see that the 67 shop manual lists a 11.5 inch as being correct. I'm a bit confused as to what I have - The car came with a big input toploader when I bought it. The big input clutch plate that was used was only 11 inches, so the wear pattern on the flywheel is this size (any issues with going to an 11 1/2 clutch and not resurfacing the flywheel?).
My bellhousing is C60A-6394-D, which I believe is correct for a 67 with the 390 (and for an 11 1/2 inch clutch). Is there a difference between 11 inch and 11 1/2 flywheels?
I'm thinking it's probably simpler to just stick with the ll inch clutch, even if it is not 100% correct...
