Took these pics for Kokamo but figured they may help someone else!
I made this undertail out of a rubbermaid can LOL. I took the side panels off and used a piece of cardboard as a template. Then cut a piece out of the can and got it to fit the way I wanted, test fit the side panels, and once I was happy painted it black!! Works for me!
while I was at it LOL
OK i'll quit!!
