1964 and 1965 Barracuda Reproduction Rocker Trim Clips

Thanks DC340 and grimreaper, this is the very helpful. I was thinking it was all about the height of the clip, not the shape of the surface where it mates with the rocker panel. I can see how the original clip would draw the molding closer to the rocker, as it is thinner in the middle and has the curved backside.
