clutch plate diameter

i need a new clutch. there is a 12 inch diameter, and an 11 inch diameter. the truck has a 350 with the granny gear tranny. its also a 79 custom deluxe. anyone know what size it should be?

I believe either one will fit. Cross reference the pressure plate part #s to check for any difference.
