Demon / Duster 1/4 window mods (roll up)

So I took a field trip today to pick up some parts for what I think will be a good start point for this attempt. Best part was the guy has several and had some still in the car with the 1/4 off so I could see how the glass travels. The pics are of glass in a 70 Chevelle, the parts I picked up are out of a 70 monte carlo exact same car. Based on how the glass moves, seals etc, I really believe that window frame in a Demon / Duster can be modified to allow a custom glass window to function in the exact same manor. As you can see the Chevelle window is curved very close to the same a Demon / Duster door glass…
