Called Van's parts desk since I hadn't heard back regarding the FWF parts list I sent them on Tuesday evening, 11/14. They said they were about a week behind on emails and would get to my list and send something to me for review/approval. Modified bends of COM antenna doubler for a final good fit. Match drilled doubler to fuselage skin, deburred and dimpled skin and doubler with help from Ellicia and her twin ;-). Realized my original plan to use a blind rivet to attach the doubler to a previous doubler creates a problem. Decided to use a technique I saw in Kitplanes so I started making a wedge to use between the rivet and the puller to allow me to tilt the puller at approximately 10 degrees to clear a flange. Hope it works. Tried several different methods to modify the ID of the aluminum washers to fit on the showplaces static port fittings. It was hard to get a smooth ID centered on the OD with a file so I abandoned that. I eventually tried clamping the washer between two pieces of wood and using a step drill. That looks promising, but isn't good enough. I need to practice more and modify my technique. Later I searched YouTube and was pleased to see others were using the same technique of clamping a washer using wood.
