Need help determing what year, engine this radiator was for. It's a original Harrison with original core and mounting brackets, 3 row, core is 17 1/2 by 25 1/2 by 2", 1 1/2 inlet on drivers side, 1 3/4 outlet on pass side, down flow, fill hole on drivers side slanted down towards the front of the car. Presently filled with coolant and packed in a box, so don't remember the letters stamped on the tanks. Could take out and look if needed. Think this is for a 65-? BB. Thanks, Jim
