    Hello all. I purchased a race car (71 Demon) and need to replace the windows and quarter windows. They are made from what seems to be a flat piece of plexiglass (?) trimmed into the shape of the stock windows. I see companies that offer formed lexan windows that are supposed to be the factory shape. Currently the side windows roll up and down. I would like to keep that feature if possible but it is not an absolute deal breaker if I can’t. I just need windows that fit snug and don’t flop around. As you can see, there is a big gap in the passenger fiberglass door but not as much in the drivers door. But you can also see there seems to be some sort of guide used on the drivers side.

    Could it be as simple as purchasing new lexan formed windows and using factory door hardware and seals on the fiberglass doors? Thanks in advance for any advice you may have.

      Yessir! That’s actually the company I had been looking at for the replacement windows and quarter windows. I need to call and get a quote.

      So if I had those and some new seals (the current ones seem to have been carved on - I assume to make the non preformed windows fit) I should be good to go? Does this door seem to be the one to work with factory hardware? This is my first time dealing with fiberglass doors so I’m learning.

      Thanks!

        At least you started with a pattern, when I bought my Demon with the 'glas doors, I had nothing to work with. The previous owner had glassed over the slots for the windows so I had to make brackets that bolted to the top of the doors. From there, I made a pattern for a one piece window & bought a 4 x 4 sheet of Lexan at my local home improvement store, along with the correct cutter & went after it. Mine are not perfect, but they are good enough for my bracket car.

        Oh wow! Wonder why the po would cover the window openings? So he didn’t run windows at all? Glad to hear you found a solution though, I bet it works just fine.

        I have seen some cars with the metal frames for the lexan windows and they look just fine, I just thought I’d try the preformed route and hope the existing door hardware fits it and if it still rolls up and down that’s an added bonus. I just need them to seal halfway decent and not be loose and flop around so much as the passenger side does now.

        Thanks. I had not heard of this company. Looks to be a similar price if not a bit cheaper than pro glass. Except polycarbonate instead of lexan I guess.

        They are the same thing. Lexan is polycarbonate.

        Thanks. I didn’t know that. That’s how we learn! I appreciate you sharing that.

        So it seems these are very close then and price will likely be the determining factor.

        If you do a google search, there is a good online dragzine article about optic armour. There are different characteristics of polycarbonate. Optic armour is known for its optical clarity.

          Thanks Duane. I found the article. Sounds like optic armour is the way to go. I think I’ve decided to order a set from them and some new seals and give it a go!

            Let me know how you make out, I may put an order in to them myself.
