Using Alex's staple placement as a guide to where to place the rivets, I marked the metal shields and drilled a set of 1/8" holes along their perimeters. I then placed masking tape along the edges of the rubber gaskets and using the newly drilled holes as a guide, transferred the hole pattern to the masking tape with a pen. From there, it was a simple process to use a gasket punch to punch the final holes into the rubber gaskets. I did this by clamping a short piece of 2x4 in my bench vice and using it as the base while punching the holes. This gave a nice crisp hole through the rubber gasket material.
Before final assembly, I sandblasted off the original paint from the metal shields as it looked thin and of poor quality. Finished them off in the powder coat booth with a nice even coat of satin black. Once they cooled, it was quick work in attaching the rubber gaskets using the McMaster-Carr rivets. I like the look and think the rubber will stand up better with the rivets rather than the small bearing surface of the staples. Time will tell!
