Welcome to the forum, and to the busted knuckles club. Love them '64 hardtop Impalas. One of the prettier Chevies in my opinion. They look customized even when stock.

Nice thing is that you can get almost every part (if not every part) from people like Year One, and others. With that 6 cylinder stick you also probably got a 3:70 rear end, which is pretty good, and the hanging pedals are already there for a four speed setup.

Keep us posted with lots of pictures.
