yes, call a shop to do it. i used to do windshields when i was a body man, and it is something that you should not try if you have never done it. a windshield if you can beleive it is a structure part of a vehichle that helps the roof from not collapsing if you are ever in a roll over, it also helps the airbags if they ever deploy (if it is not installed properly, the airbags can push a windshield out of the truck). also, if you don't to it correctly, they will leak any time you wash it, or it rains.
