Trapezoid foam worked well but I lacked proper clearance to do both sides so top sides have extra glass only.
Decided to install 24″ trapezoid fiberglass covered foam like is used on metal roofing. Cut foam to proper shape and epoxied two of four.
While epoxy dried I installed wing tip wiring pins, connector, and grounds.
