From the part numbers I'm looking up I don't think it will fit. The 74 was a SB auto with AC....Mine is a 72 SB manual with AC....I know I would have to plug the holes for the cooler lines. What issues would I have installing....? I would measure the one in it now but nothing else on this car is original so I figure the radiator isn't the correct one and it leaks a little...The neck comes out straight instead of curved....See pic below for the radiator that is in my 72 now.
What is the measurements on center between the two top brackets? Should be 26" for a 72 small block with a/c. But that doesn't mean someone didn't put a replacement core in the car either.
A 1973-1976 radiator was 27 1/2 Inches on Center and yes the upper neck came straight out of the top tank for that application. The core on a 1973-1976 radiator measured 17 X 27 1/2 X 2 5/8
74 radiator in a 72.....?
