73 duster radiator

Hey everyone hopefully you can help me out ! I'm trying to figure out what radiator opening I have. I have a 1973 duster 340 factory a/c car and I have measured the opening and I know for a fact the 22" won't work because the actual opening measures about 24 1/2 " but the only other radiator avail is a 26" that measures 25 3/8, am I missing something here ? Please help
