64 1 barrel carter rebuld kit

Where can I get a rebuld kit for a 64 valiant with a carter 1 barrel carb with a push button auto trany with a slant six? Can you use another 1 barrel from a different year and hook it up with some modifications. It has the old rod linkage. Any other years fit? Seems like a dumb question just new to push button trannys and not sure what works with them.
