I made my own, got the material from
6″ x 12″ – Clear Polycarbonate Lexan Sheet – 3/16″ Thick 4 $3.99 Total $15.96
I made 4, two for backup. They were easy to cut on my bandsaw. Just have to be careful. I used a template I got from James only I made mine taller to use the full 12″ of the stock.
For the hardware I went with
Wind Wings Hardware (WW H) = $60.00
