The radiator pictured is 1961 two row Harrison aluminum radiator. Period correct and if it will hold pressure a great find. I have a Fluidyne 3 row used on 427 (new) cars in the event I cant repair the correct one.
At $870 for a good repop I would need to really have issues with Fluidyne. I know they work splendid so that will probably not happen.
Wish me luck with the repair....
