    I bought this awhile back and finally got the car in the shop to work on it. This is the Summit brass/copper heater core similar to the one I put in the 1970. Same manufacture. See
    Says it fits 63 to 68 Non AC.
    They did not offer one for AC at the time. After looking at pictures it appears to be the same so I ordered it. With the old one out for comparison it is very close. See below:

    They now carry a copper one specified for AC cars: Spectra Premium Heater Cores 94539
    The upper nipple on the old one has a slight bend to it. We'll see if it is really necessary. The Spectra has the bend.

    Follow-up: Just to document, the straight upper hose connection gave me the extra clearance for the 455 valve cover I was looking for, BUT I did have to notch the firewall hole for it to clear without rubbing. The bigger issues will be the lower connection which will require a 90 degree bend to bring the hose out from behind the head. I think a hose with the bend cut close to the firewall will work, I just need to remember to put it on before the engine goes in!
