I need help identifying if this radiator is a 1969 Nova big block. I think the curved neck has been replaced but I am not sure about the tank codes. The left tank is IL and the right is ON.

This appears to be an auto tranny radiator...the IL code is correct for BB Nova...as for the ON

Only code I can reference is OM for 67-68 BB Auto in a Camaro. Nova and Camaro radiators [68-69] were pretty much the same. Carried over to 1970 for the Nova...

The ON code is a new one...perhaps others can help.
