Fanbelt problem

Ok, heres a dumb question. I have a '67 Dodge Dart ragtop, slant 6. Stock as far as I can tell. I replaced the bottom radiator hose and discovered that the fanbelt had been rubbing the hose. I figured the hose might have swelled causing the rubbing. When I ordered the new hose and installed it, the same thing happened. Am I missing something? Is this a design flaw or am I just doing it wrong. The hose seems to be the right one. Any suggestions? I really want to get this thing ready for the warmer weather.
Thanks'

When I was getting my Dart slant going a couple of years ago or so, I had a terrible time finding a lower rad hose. I tried the Goodyear 60664, it fit but didn't have that subtle bend around the bolck so the fan belt didn't rub on it. Tried a Kelly-Springfield s-105, not really close (both came up on the Kragen auto parts store as fitting).

What fit like a glove with the perfect bends was the Gates (which make NAPA's hoses). Gates 20949 or NAPA 7674. I have a 73 Dart with the 22" A/C radiator, so yours may be different, but if you haven't tried the NAPA or Gates hoses, you may want to give it a try.
