The price is reasonable enough, but I would rather use a countersink on the holes and use some little hot rod flat head screws and lock nuts.
I prefer to use clips. All the plexi/lexan that I have seen installed with rivets or screws (even with minimal torque) crack from the screw holes eventually. When I installed the one in my Saturn I used small clips bolted to the body for the top and bottom with bolt on channels on the pillars.
I agree with TT that screws are better than rivits.

...well with the back cutting for easy attachment, you don't have the thickness for counter sunk bolts. Plus with the nut and lock washer arrangement, it is then a PITA.
Here's a picture of the back side...I hope:
is there any way to put it in like a stock window same with all the windows? have never had any of this but know some one that has a tone of it and said he would cut it for me to fit.
just for his cost of material. aka free cut and fit

77turbopinto hit the nail on the head about cracking. Any kind of hole is going to eventually crack through. I know that screws take longer than rivets, but if there is room enough for rivets, there is room for screws and it makes the difference between so, so and really nice. Don't use lock washers, use Nylocks. Hell, I even turn all my screw heads the same direction.
Looking at the pic close up, I would say that the bevel on the lexan is way to much causing the mating surface to be too thin for use. You don't really need a bevel at all. The thickness of the Lexan is just right to make it flush with the top and cowl.
Listen to the old guy as he knows of what he speaks. When we put the lexan in our funny it was done with a zillion, ok maybe just a million screws and nylocks. We never had it crack and the car was over 200mph and virbrate bad. You get an electric screw driver and one person on the outside and one on the inside and just do it. Everything else is just kidding yourself but it will also give you the opportunity to do it over again.

You
could use the stock rubber gasket on the pre79 cars if the windshield is about the same thickness.
Than being said there are other issues too. You will NEED some sort of center support(s) as the 'plastic' is way too flexable to be unsupported, and those supports might not be 'street legal' (the windsheild might not be either). It would be a challenge to install a flat piece. Also, as mentioned it WILL vibrate regardless of mounting or supports.

First all PC windows are not DOT (Dept. Of Transportation) or street legal. You might get away with the rear 3x (many Cal Look ACVW street racers do...) but check your local laws!
You don't need a center brace on these 1/8" thick windows as with the mounting and bowing it increases the strength to prevent flexing in at speed. I have many ACVW customers running them over 150+ MPH!
But I can also make them in 3/16" material too. I also stock single side (to keep the costs down) hard coated PC (not the off the shelf stuff but a local millitary PC supplier coats them for me) for those wanting that too.
But I have had several of my customers run my std. PC on their drag cars for up to 10 years as along as they follow the written instructions on caring and maintenance of PC windows
All alum, over size head, 1/8" rivets are the best fasteners for PC windows as they hold the PC at the proper tension. The secret is having the hole slightly oversize to allow for expansion and contraction.
1/8" thickness sticking up is not flush mounted for my customers.....
But I only have been making PC race car windows for 25+ years for the Air Cooled VW industry (did you see the last Herbie movie, Monster garage with the swamp Bug or the Pink's show with the ACVW Community build Katrina Hurricane relief vs Honda episode.....then you saw my products on them) with doing maybe 35+ sets per year! Open any Hot VW's magazine and if they have PC windows (stock rubber or flush mounted), then 90% of them..... I made them.
