    Hey guys, I'm working on a 1978 with a sbc 350 with A/C. It originally had a 3 row in it.... after testing it I found a few leaks so it is no good. I have two spare radiators both identical to the other radiator that was in the 78, the only problem is the upper inlet is smaller in diameter than the other radiator. So basically the upper hose is too lose and won't fit in tightly.
    Why are they different than each other? If I can adapt it to work, will I have any problems or should it work like any other normal radiator?
