I am starting to do some reassembly on my 69, I bought new bolt kits. I have a package marked radiator well nuts. When I tore the car appart, I never came across anything that resembles these. Can anybody tell me where, and how these are installed?

Hold your rad in place and you should be able to see where they go on the driver side of the core support. The pass side bolts directly to the core support, you push the rubber well nuts into the holes in the support and attach the rad to them...

You can see how it works in your AIM under radiator section...
