I've wanted to get this done since I've owned this car. Because the paint is so ah, weathered, from some angles they go away. I'm very happy with the results. Thanks Rick and Jeb. And thanks to Tuck for the pix of his awhile back.
Buck a hole, plus set up charges depending what has to be done. They just do it mostly to help friends out. They don't advertise or anything. Rick told me he spent about 6 hours on the whole job.
It's a machine. An old rivet press they modified to punch louvers. One hole at a time. You have to line up every one! So I'd say it's a combination of machine and man. Here's another angle.
