I'm currently restoring a '67 vert, and the radiator that was in the car seems to be incorrect, and I've not been able to identify. It has the soldered on large tag as on 68/69's. 21" 2 row core (automatic) Harrison with IA and CS tanks, coded as FH. Anyone with an idea as to application ? Part number at bottom of tag is badly rusted, appears to be 302?300
