Next, install the side bows to the header and top fabric that’s been out in the sun. You have to remove two small screws per side to access the holes you will use when you put screws into the side bows. Take note of the orientation of the hook-shaped bracket on the side bow, shown here. This is with the bottom of the top facing down and the header folded over the top. With all four screws installed (per side), we stuck the foam over the screw heads.
