Not an A body guy, but . . . Floor pan question

Does the 66 Valiant need a full floor pan or just patches? Auto Body Specialties has all 4 patches for early A bodies such as the 66 Valiant. Several years ago, someone on here used an AMD full floor pan from a 67 - 76 A body in an early A, but it took a lot of work to get the middle of the pan where the top of the transmission hump is, to match up to the firewall. Sides needed to be trimmed off a little if I recall, but he said that was easy.
