Time: 1 Hour
Along each side of the pilots legs is a side panel of sorts. There is a solid cover that goes on these areas. On the left the fuel selector valve is housed and on the right is just solid. I decided to add a cup holder in the right that I found on amazon for a few dollars. It’s black anodized aluminum and I added a layer of neoprene to the inside to help pad a drink. The holder was epoxied in place and then both panels screwed down. 
I added the cover and valve handle to my Andair valve and it looks awesome.
Did you build or purchase the side panels where you have mounted switches? It may be easier to reply to my email address at Dave.Pyke@gmail.com
