I've had my finged singed a little a couple times, but that's neither here nor there. Let's see if we can help you move on by figuring out what you have.
If you have either of the radiators mentioned in the first post, they will not work in a '72. However someone with a '68 or '69 would probably quit ewilling to buy it from you.
OER is a misleading trade name because its easily confused as OEM, an abreviation used for decades by antique and classic car restorers as well as the industry.
MA2246A - 1967-69 Mopar A-Body Small Block V8 With Automatic Trans 3 Row Replacement Radiator
This item is 1968-9 v-8 A-body replacement. Prossibly ok for '67 other than the fan shroud fit.
Radiator 2949066
if this is what you have, Steve said that's a '69. Again not for your '72 but is fairly valuable, even just for parts. Glen Ray will certainly give you something for it.
if you have something else, post it up - start a new thread - ask what its for and I'm sure people will help out.
