I used Goodyear 60664 on my 64 Valiant slant. It bends aft to clear the alternator belt. My radiator also has a straight lower outlet on R side. Definitely not a stock radiator and probably not even for a Mopar. It was on the car as bought, along w/ a "Honda" battery, and M-B electric pusher radiator fan (no mechanical fan). The slant doesn't leave much room. I had to get just the right thickness after-market spacer to install a fan, and no room to fit even a thin M-B clutch-fan. Note how they offset and recessed the water pump housing in the block to squeeze the long slant into the early A's. Later cars might have a tad more room.
