Hope that might work, I do not seem to have the image on my pc, it is out there on the internet in several different places, hope you can see it!
on my car it was actually leather!
I did experiment using nylon (which Britax Weathershields used on the fabric sunroofs from the 1960's to 1980's) on a spare sunroof panel I had at the time, this did not work as well as I hoped as it did not run smoothly over its route - the nylon is not very forgiving with an uneven track.
I tried leather, but this did not work and I did find glueing was not a serviceable option on its own and fitting rivets meant that the rivet became the slider, needs to be well fixed so it is buried in the material.
From memory, the leather was not really thick enough.
In the end, the spare sunroof panel (which I thought was original to my car, wasn't, it was too short, so sold it on) and the actual original sunroof panel (which was not in such as good as condition as the spare, which is why I used it on the first attempt) had its original sliders, but these were worn, left these in place for the sunroof that is now on the car and works ok, only trouble is that it is that is rattles... A wedge has sorted that out...
