'69 L 48 Radiator 3 Core Tag

[tmodel66]

My radiator tag is rusted so bad I can't read it. It is also a 3 core radiator. It does not have A/C. I read in the CRG reports that sometimes a different size radiator was used if there might have been a shortage or something. I am going to replace the radiator and I was wondering what tag would have been on it. It has the CB and IH tanks.
