When you take off your bed there is nothing to hold on the fibers so you have to build mountings that connect to the frame and towards the top of the fibers there is a picture on here go to page 2 under my name again and fishdood and a lot of other people showed there mountings!!!
The MOUNTS you are refferring to could be called rear glass supports. The person fabricating this for you shoud know what to use if he is building them for you. The mounts are not off the shelf items. Use mild steel and some dzus fasteners to hold the "fibers" on.
