The build manual has a two piece backing plate for the fuel level sight glass. I cut and installed the two piece backing plate some time ago but was never that happy with the two piece design. Recently I was about to cut and attach the graduated decal to the backing plate while it was installed in place on the wing root rib. I experimented with some paper copies and quickly realized that getting the decal in place smoothly was going to be a challenge. I came up with an alternate idea that I'll share below. I fabricated a one piece backing plate of similar shape to the two piece design but with with a couple of small cutaways that allow me to slip it into place. The pictures below show the two designs and how the one piece design goes into place. I haven't installed the decal yet but it should be very simple to do now before the backing plate is installed.
