Will a carburetor for a 82 Honda CX500 work for a 79 Honda CX500?

I just bought a 1979 Honda CX500 for a good price but it doesnt have a carburetor. I found a carb locally thats like brand new and its a good price but its off of a 1982 Honda CX500 so before I buy it I was just wanted to make sure itll fit.
