We carry a full line of our own Plexiglas front and rear windows for Shelbys and Mustangs. These aircraft quality windows offer large weight savings along with added safety and strength. Accurately thermoformed by the same process used to make NASCAR Cup racing windows. Not just a piece of flat material, these windows have all the compound curves of a piece of factory glass for an almost undetectable look. Made slightly oversized for a “trim to fit” installation. At ¼” thick they use the stock gasket, moldings and clips. These windows have been known to run for many years with just periodic polishing. Save up to 25.5 crucial lbs from the top of the car for a lower center of gravity. Rear R-model windows are an exact reproduction of the originals with the “iconic” dip down 2” opening at the top. This was a Pete Brock innovation claimed to add 5 MPH to a car’s top speed. The R-model rear window installation kit is a reproduction of the original set-up and includes 2 spacer channels, 4 hold down tabs and the front center support bracket all made of aluminum. Plexiglass windows are not DOT approved for street use.
