I didn't mean to stir up unrest but I replaced the original radiator in my 1969 panel with a new, all brass Harrison that I found at a local O'Reilly's. They told me that it was a regular catalog item and the price, somewhere around $125 was standard. There is a tag soldered to the top of the back of the upper tank that says "Harrison" and it is a 4 row. I bought it because it was $50 cheaper than the stock 6 cylinder single row radiator! I had to replace both the upper and lower metal mounts and the rubber inserts in both. I added a 350 fan and fan shroud to complete the cooling system. With a 190 degree thermostat that's where the gauge sits, running hard or long idle! This was my goal.
