Need info on 72 A body bucket seats

I recently acquired a set of 72 A body bucket seats from Tony's parts..I've been looking for a set of 71's to put in my 71 Demon but are difficult to find..The 72's need upholstery and some foam reinforcing..Apparently they don't make new foam for 72 seats so I was wondering if 71 foam and upholstery would work on the 72 seat frames?..Any help would be greatly appreciated.
