Getting ready to re-core my original CB/IH-C Harrison radiator. One of the rails has a small hole drilled in it near the center of the rail. In my haste to disassemble the radiator I did not notice this hole. Can someone tell me if the rail with the hole goes on the top or the bottom?
Look here. I think there is a picture part way down...Joe

The top and bottom are the same. Put the worst one on the bottom side.
If it has a hole in the center, someone added it. Both rails are a matched pair.
