Mike, on the windshield be sure to have some help. Make sure its lubed up good and pay attention the corners and the center strip. Its not a hard job, just take your time and be sure to "lay" the sealer to it as recommended in the repair manual.... and if you have the stainless trim it must be put in the rubber gasket before putting the windshield in the truck. Fit it all up good and let it "form" for a day. Let us know how the deal on the rear window turns out. That's a lot of misfit there!
