What we do is take a rigid wire like a tig wire or coathanger and form the shape we need and head to the auto parts store. Our local one lets us dig through all the ones on their wall until we find a match. We measure the radiator and engine nipples and match those to the new hose we buy. We usually have to cut a little off to make a perfect fit, but it works.

When I swapped the 5.0 into my Jeep truck I had a real tough hose to match up, it goes on a crazy angle. But by doing the method I described I found one that worked perfectly.
