Bob I bought the same replacement radiator that JC Whitney is selling.
Beware! It has 15 fins per inch instead of the 20 fins per inch on your OEM radiator, and smaller tubes. The same radiator is available on the internet for $470.00.

Your OEM radiator does an excellent job of cooling. Get it repaired.
I am in the process of adapting brass end tanks to my OEM radiator and junking the replacement that I bought on the internet. Just one of the mistakes that I made with my F53.
