I am trying to figure out the best way to attach the boards to the frame and was wondering if anyone had advice. The kit comes with a bunch of screws that are supposed to be used for attaching 2x4's. i think they will be too long to go from the back and then through the board. i am also not sure how will they will hold going from the board to the frame. I thought i would ask here instead of doing trial and error. Here are some pics i found of what i am trying to do but couldnt really tell how it was attached in the pic:
