I don't know what they are called, but I do know of what you speak.
Father had a F100 styleside canopy setup that way. Remember as a kid hopping from the front into the back when away on trips. (bench seat bolted in the tray for us kids. We did have seatbelts
the good old days)
Was like a heavy shade sail material with a weatherseal either side. Used to freak out getting my fingers squished as the body flexed.
Would think contacting a fiberglass canopy mob would get the best results maybe.
