1963 to 1964 Catalina front sheet metal swap, can it be done.

I am new to this forum and hope someone with more knowledge than myself can tell if I can swap out the front fenders, grill, bumper and hood from a 1964 Catalina 4dr hardtop which I put into a guard rail a couple of nights ago with a 1963 Catalina 4dr sedan that I can buy from a guy a few hours north of me. From all the photos I have been able to see it looks like it would be possible but I'd hate to go buy the 63 parts car to find out it won't work. Any help on this would be greatly appreciated. Thanks, Bob
