'64 and 65' Flywheels

I have a '64 GTO with a 389 Pontiac motor out of a '64 Catalina. Are the Clutch and Flywheels the same in a '65 GTO or are there differences?
I've read where the engines of the '64 and '65 GTO's take the same clutch and flywheel. I've measured the clutch and flywheel in my car and they have a 10.5 in. clutch and 13 in. flywheel. Can anyone give me some info on if there are differences. Someone told me the '65 GTO had an 11 in. clutch and disc with a slightly larger flywheel.

the clutch disc matches the flywheel size. It could be any size now because you don't know if it is still the original setup, I doubt it, so either size if matched could be installed.
