Fix my orignal radiator or just replace??

If you are enjoying driving your car, do so fairly often and don't need or care about the look of the radiator, then a Performance Aluminum radiator will cool better and cost a lot less than restoring the original radiator. I would absolutely save the old radiator in case you or a new owner ever wanted to restore it back to original. If you have kept your car totally stock and don't drive it except to shows, then Glen-Ray is the best way to go.
