Radiator identification
Glen-Ray radiator has the correct cores, most shops do not. With a factory big block A-Body radiator you will have 1/2" tubes instead of the normal 3/8" tubes, so make sure if you have it recored that you get the right core! They can also provide the correct part number tag that yours is missing. If it is just a pinhole, a competent local shop can fix it for you.
