Lower radiator hose

[46HARLEY]

I searched and did not find what I was looking for, so hear I am. 1946 Deluxe. Need to install lower radiator hoses and heater nipple. What is the best procedure, having not taken the old off yet. Cut to fit hose or not, if I do best length. Best way to install, I am sure no easy way. Looks like even more pain with the heater nipple installed, like to hear your method of installing that also. Would love to see any comments on this. Thanks Larry
