Another champion radiator chapter with pictures

i have the 26" 2 row from the guy on moparts, i couldnt get an accurate measurment of the core thickness on 2 and 3 core. so i just went with the 2. what size are the tubes in the 3 core? i heard the 3 row has thinner tubes than the 3 row. that was another thing the guy couldnt tell me that i had bought from. i dont understand why they put the overflow on that side. thats just stupid. i was going to cut the neck out and recess it down in to the tank so the cap would be flush and point th eover flow the right way, but i took the lazy way and just bent a piece of brake line up to run over to the factory overflow.
