I'm working with a couple trucks, a 41 and a 53, and was wndering if anyone would share some tips or dimensions for the two board sideracks that make these trucks look so neat and finished.

My plan is oak 2x2's for the posts and 1x3's for the rails. First, is this a good proximity to what others have used (did I buy the right stuff??)? Second, what length is best, even with the end of the box, in slightly, etc?

Any advice would be greatly appreciated.
