Like someone said before, BEEN THERE, DONE THAT.
Do yourself a real favor if you are going to have someone local put your glass in, shop around.
I punched mine out last year for the first time.The first 3 places I called wanted over 500 bucks to install a new glass. I was real bummed out!
The fourth and final guy I called wanted only 175.I told him that I didnt want some cheap piece of glass, he told me that he only installed OEM quality glass.
When he showed up, I checked out the glass and then checked the name of the glass company online. Lots of good feedback so I told him to go ahead.
Four days after he installed it, it fell out while I was driving down the road.I called the guy, and he came right back out.Luckily the glass slid down between the cab and the bed and rested on the frame rails, so it was undamaged. He called the manufacturer, and they told him to use a different bonding agent which he did.Had no problems after that.
Why he was so much cheaper, I have no idea. Maybe he stole his glass at night?
