Barracuda 273 9.5 inch clutch

I have the 2-barrel version of the 273 in my 1967 Barracuda with an A-833 four speed transmission. I have the 9 in clutch and want to go to a 10 in clutch if possible.

Does anyone know if the bell housing and flywheel are the same for both the 9 and 10 inch clutches? I seem to remember reading somewhere the 10 inch clutch used a larger flywheel, therefore a different bell housing due the the diameter of the flywheel and starter placement.

Is it as simple as finding an A-body bell housing and flywheel out of a car that had a 318 and 10 inch clutch or is it possible to use my existing 9 inch bell housing and flywheel?
