Here I replaced the factory glass with lexan for saftey and weight reduction. Below is a picture of the factory glass in the rear windows.
Here I used the factory glass to make the new lexan windows.
Made sure the new windows fit and did any trim work.
This picture was after I drilled 1/8" holes for rivets and I had already painted the inside outer edge black to cover the frame work behind the window.
Last I made sure the top trim would fit back into place with no problems.
The weight savings was only 3lbs, but my plans is to replace all glass with lexan and that should save a lot of weight. Besides it's safer!!!
