Followed all the instructions stated in this thread. I wasn't able to find a U-shaped metal bar in my little hardware store around the corner so a L-shaped one had to do which works just as well. These instructions are awesome and worked out perfectly. It holds the pull down much better and more solid than before and it won't come apart anymore.

While I was at it I also put some tape along the seam, which comes apart on many Xfires so people won't cut their fingers on those sharp corners.

Thanks again for these great instructions including the pictures. I can urge everyone to save yourself some money and do as shown here!
