Can you tell me what these radiators are from?

[Chargerguy74]

I've got a couple rads that don't appear to be correct for the Chargers they're in.

One is 3869963 the other is 3692998. I'm guessing mid 70s? Any help would be appreciated. They aren't listed in my 62-74 part numbers book. Thanks!

I'll say 1978 or later, maybe they're early 80's based on those part numbers. The first two digits of the part # will give it away. I wish I had a reference for you.  Mine is just a guess...

The last number I can find reference to is 3692978 and that is 1974.
Try doing a google search using "3692998 radiator Mopar" see what happens.

Yeah, no luck. I guess it really doesn't matter what they're out of. Incorrect is incorrect. But they're working just fine.

If you really need to know, I'm sure Bob at Glen-Ray can tell you.

the GGovier casting book does not have a listing for 3692998, but the 36929xx is for a 1974 radiator. 3692978 is is a C body 440 radiator 28"
