Drilled and tapped for 1/4-20 stainless machine screws, red Loctite to keep 'em there. Rubber washers and short section of neoprene tubing to cushion the 1/4"poly-carbonate. Thank you!
Stig, over on the scooter side, took the time to coach me on posting those pictures. Without him this post would not have been possible!
