OK, got the clips from these guys.

Part number FC9546 Box of 50 for $8.85.
Below are pics. Instead of painted, they are cad plated. Less then .002 inch difference in the thickness of the metal. More importantly, they are dead on for the height. Both the original and the cad plated ones are .650 inch high. The UFO brand and the ones I got from the classic car vendors are all .737 inch high. Using the .737 clips will result in the molding sticking up above the panel almost .090". Simply not acceptable.
You can see the difference in the pic below. One of my originals in the middle, new cad plated one on the right, and the other two (one UFO and one from a vendor) on the left and left upper.
