I don't understand how these people make windshields the worst way possible. AP Tech does a great job of urethane the bottom pieces on, but then they use double sided tape to hold the mirror brackets on....We've had 8 fall off this week. DUMB. PGW and Pilkington like to double side tape the bottom pieces on that clip in the cowl, but half the time they are all screwed up when you get them. Then you say, hey get me another one...ohh they are all like that. Engineers are worthless. It works in theory but not reality.
