mine was just a guess. Sounds like the jury is in... don't try it is the verdict.

every one that says you canot cut,drill or grind the back window is correct.I worked in a glass shop for 10 years and figured if a guy figured out how to cut tempered glass he would be millionaire to say the least.laminated safety glass can be cut .most glass shops can cut all your flat glass for your hotrods if bring in your old cracked glasses.and I bet it will be alot cheaper than some I have seen in magazines .you will also have better options as far as shades good luck

I drilled a hole in a tempered side glass once just to see if it could be done. Of course I was told it couldn't be . I used a diamond coated bore. Drilled right through. When I lifted it out of the water it disintegrated into about 2 million little pieces. So I'd have to say " nope, can't be done with tempered glass. Laminated glass on the otherhand drills easily but will stress crack if the hole isn't smooth.
