Attn: Gwen

I checked with a friend of mine who runs an independent parts store
regarding your quest for an upper radiator hose. He checked his books
(books, mind you--not computer) and even ordered another book from his
supplier to check some more and the only formed-to-fit radiator hoses he
could find for a 63/64 Classic were for the 195.6 ALUMINUM engine. 

His suggestion was to contact Gates directly (www.gates.com) and inquire
with them to see if there is something they could do to help you get one. He
said it's a possibility you could get them to make one for you. Gates is
pretty much one of the longest-lived hose suppliers out there and in many
cases was the OE supplier for several automakers. 

Anyway, there's the info, for what it's worth!

Hope it helps.
