Hi Cory, welcome to the group, Pop-Up top Division.... LOL
If your top lift supports look anything like the ones on my Hunter Compact-II the sliding parts are off-the-shelf heavy duty drawer slides available at most large hardware stores. Below is a pic.
The edging I use is standard "Knock-On" edging trim, available at automotive upholstery supply houses. It can be had with the sealing tube on the sides or top edge. You order by the foot and based on the thickness of the material you are using it on. Places like J&J Auto Fabrics in Rialto, CA will send small samples on request. (jjautofabrics.com)
