help 1964 Slant 6 tune ups specs

I was looking at my upper radiator hose while I was working on the car. I noticed a little leaking from the upper radiator hose after changing the thermostat. I would like to replace it, but there seems to be so many different part numbers on rock auto. I think the one on the car is the Gates flexible hose. Is this the best choice for my 1964 Slant 6?
