I just went through this with my '71 charger with tinted glass. I needed windshield and back glass. All of the used stuff had problems: chips, deep scratches, pits etc that I probably could not polish out. A local shop had an extra AMD tinted windshield for an excellent price so I bought it and it fit perfect. So I thought I would try the backlight from AMD/Jegs. First one came in with a 10" diameter hump on drivers side that was about 1/4" high. I could not attach my dual suction cup handle to that side. Pass side was flat so the handles would seat here. You could feel the difference with your hand. Defective glass was returned for exchange. Second one came in with same defect. Sent that one back and Jegs called AMD and they found that all of their stock had the same defect. Now back to search for used again. Glad that shipping was taken care of and they refunded my $. No gripe with Jegs but I wish AMD would have checked before sending X 2.
