Need Help with Front & Rear Windshield Installation - Duster

cudamark has it dead on the money. The only thing I'll add is, make sure the window channels are SPOTLESSLY CLEAN. Also, after you get it done, rince the liquid soap out until there are NO suds at all and let it dry REAL good. Then, you'll wanna apply some kinda silicone based sealant all the way around the outside of the gasket, under the outside lip, between the lip and the windshield channel. Lastly, to me, car glass has always been like tires. The bigger the glass, the easier the install. The smaller, the harder the install.
