After taking care of some family things and traveling for work, I finally made it back out to the shop. While I was in the Atlanta area for work, I stopped by Aircraft Spruce in Peachtree City and picked up some 2 x 2 x1/8" extrusion and extra hardware. The extrusion was the material that was not supplied in the kit. Sonex sells the parts individually for about $2 each. I bought 2 feet of extrusion for about 4 dollars. Now I have plenty of extra for other uses during the build.
I fabricated the -06 Angle Clips called out on WIX-F15 and also worked on the clips on WIX-F14.
