Use wood screws to attach the solar panel mounting board and the project enclosure to your mailbox.  I had originally drilled the solar panel mounting holes straight down into the mailbox post, but it is better to drill them at the angle of the mounting sheet so the heads of the screws sit flush with the solar panel board.  I had to make a modification to the mount board by attaching a thin piece of wood to the back of the acrylic sheet so I could counter sink the screws to correct this issue.
