Need 66 Barracuda rocker fasteners

Has anyone come up with a diffrent style lower rocker cover? My car had all the studs and screw holes removed years ago. Now that the car is on the rotisserie and the sand blasting was dont I can see where they go but not sure how to re attach them. I was thinking about taking the ones I have (albeit a bit road worn) to a machine shop and get the units shaved down or made new from billet aluminum but with a diffrent pattern or scallops like the Hemi Cuda from 70-71 style. or even a fish scale pattern. Again just thinking outside the box to be diffrent, Anyhow, then a diffrent type of mounting can be incorporated.
I want to thank 4spdcuda66 for starting this thread. Made me remember I need to address this sooner than later.
