Early A experts, opinions wanted

As if I needed another project, but.....

My youngest son will be turning 16 soon. Found this '63 Valiant and it's speaking to me! Might turn into his birthday present. Price is right and it might run. I've got enough 2nd generation A body parts to get it going. I can find the obvious rust and I'll be looking at floors, frame rails, trunk. Anybody see any problem areas here? Anything hidden that I should be looking at?

Thanks.
