I've thought about doing this on my car but so far it's near the bottom of the list. I figure there are two ways it could be done without comissioning a run of 1000 sets of safety glass and going into the cal-look 914 business.
1. Polycarbonate single piece windows
- Easy to fabricate, all you need is a template, a band saw, and some kind of heat source to give it a curve.
- Attracts the racer crowd because they would probably be lighter
- Might be able to forego the window winder for a simpler up/down slider
- For the serious racer you could have a simpler setup of windows that just pop in and out for rainy race days
-OR-
2. Cut the window guide off at the top of the door. Connect the window, the chrome half of the window guide, and the vent window together. Move the bottom part of the guide forward towards the door hinges. Have the whole thing go up and down with the window crank.
- Keeps the original look
- Special pieces can be sold in a kit and the buyer re-uses his or her old glass
I don't mind how the vent windows look from the outside of the car, but when you're driving they kind of take away from the 'open' experience and the fact that they're not functional always kind of bugged me.
Anyway, like I said, I've thought about it a bit
