Check it off the list.

I was putting this off, but it was easier than expected. It cost me $50 for a 55"x11" sheet of .250 Lexan. I then stopped by a friend's shop to trace a stock rear window onto the Lexan.

Once I sort out the covering for the firewall, there will be some additional rivits along the bottom.

What weight difference did you notice between the glass & lexan ?

Plus is the metal strapping just a temporary thing while the butyl cures is it that going to stay? Is it really required??

Sorry for all the questions, just about to do this myself.

I got a 1/8 sheet of 4x8 lexan for about 80 bucks. Had to make a hi tech liner for the chicken coupe. I have some spare pieces that could turn into something useful?

the straps keep the window from blowing out (or in) when the car starts spinning at 100mph. Should have them on the windshield also.

that's why those NASCAR guys need them, they know a thing or two about going sideways and backward at speed. (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif)

There's no adhesive. The window is screwed and rivited in place. The aluminum strips are necessary because the Lexan is much more flexible than glass. They are the primary mounts and are rivited to the roll bar on top and screwed to the firewall at the bottom.

Not NASCAR, just race car. (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif)

Nice work Joe! Did you get the wheels back yet? Any pictures? You are making great progress.

You should use some type of calk. maybe some tub and tile sealer. Nothing serious, just something to keep the water out when you wash that beauty.

No wheels yet. Those f'ers can't seem to deliver anything on time.

Tomorrow or Thursday.

One of these days when the rear window on the race car loosens again I plan to put in some lexan. Not for weight reduction, BUT just so I can make a small sliding opening like the 917's have. I plan to close it at the start of every race just like the movie........

I did the same project a few months ago. If the interior is already gutted, it's not too bad. I did seal the edges with clear silicone however. Instead of straps all the way across I just made some little aluminum hold-down tabs that bolt to the stock shoulder belt hard point. So far I have not noticed any flex or desire for the lexan to jump out of place. It sits fairly snug in the recess so would really have to flex severely to blow out the back.

I must admit however that I haven't tested the 100mph backwards thing... (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif)

No, I had a concept of financial suicide. (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)

I don't need a GT lid, I need an RS lid. What's an RS lid? (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif)

I put a lexan rear window in my 6 some time back.
I put the original glass on a digital scale and it's weight was 8-8-1/2 lbs.
I also used 1/4"lexan for the window,and after all the trimming to fit it's final weight was 4lbs.
Unfortunately,after I was done I miked the original window thickness,and it appears I actually should have used 3/16"lexan.Probably could of saved another lb. or so.
