Foxbody removable windows?

We used 1/8" masonite for our Fox Mustang windows. Its flexible and easy to install and remove. For our latitude (Kansas) the plastic gets very brittle for our early and late season events (some with snow) and eventually cracks. I'll get the name of the material for you shortly. We took a stock window and used it as a template for the wood material windows. We then secure it so it doesn't slide down and fall out (inside the car) with that piece of particle boardish material you see at the bottom of the window. On the inside its secured with two washers and wing nuts so it doesn't vibrate out while traveling to and from the track.
