Trying to clean out the shed. I have an original '65 GS radiator--3 row out of a non-AC car. It consists of the passenger side tank and the core. I used the drivers side tank off of it on mine when I had it re-cored.
Additionally, I have the original 4-row AC radiator core that came out of my '65 GS (core is no good) and it has the driver side tank still attached to it. The reason I didn't use the drivers side tank is because it has the two transmission cooler connections soldered over--it was leaking coolant around the ports and at the time I did it (before I ever restored the car), it was easiest to just solder them over solid. So it definitly doesn't leak and looks really neat and tidy--just not for a 400 point restored car.
You could take that tank and put it together with the non-AC radiator missing a tank and have a good radiator.
All of it for $50.
