OK, I have been to the CRG site.. lot's of good stuff.. but doesn't answer my question
My radiator has a copper Rad tag attatched to the cooling fins on the pass side at the bottom... not on the tank..

it is marked
^^ 19
0950337

also on the Pass side about 3/4 up on the tank is

IR 337
M19985

Looks right for the car... mounts correct...

Thanks.

the 337 is the DPI part number for the radiator
it is the right radiator..

so aftermarket replacement?....

THanks.....
I'm gonna sell it and wanted to make sure it was a true Camaro replacement..

Pardon my ignorance... but just what does DPI stand for?....

DPI stands for DATA Point INC. They are a part numbering and information management company for the radiator industry. 337 is the number that the industry uses to refer to the radiator for the first gen camaros

The radiator that you have is a Modine (brand)
