The order for platenuts from Aircraft Spruce arrived two days after I ordered them (first class). Meanwhile, Van's finally got around to telling me the power supply was backordered - big shock. So I canceled that and told them just to send the hardware which they did. Advantage: Aircraft Spruce. Van's customer service is the worst I've seen since 2001. It shouldn't take two hours to install four or five platenuts but it did because of the convoluted way they have to be match drilled. I marked the interference spot in the passenger-side panel, removed the plate and filed it away and then installed the platenuts after drilling out one hole to #27. Deburred, dimpled and riveted them in place. I'd already drilled out one platenut on the pilot side but needed to match drill for the platenuts there and I did that, deburred, dimpled, and riveted them in place. I found one interesting thing. In the instruction for the right side for the Dual Garmin G3X, it says you need to countersink the attach holes - something like 47 of them I think. The nice silk screened and powder coated blanks, however, do not come countersunk so I suspect they're using different hardware to attach those. I'll have to check with Van's.
