The easy way to do this is lay your windshield rubber flat on table & install the stainless, then install the glass into the rubber, then use a piece of rope & lay it in the channel with open end of rope hanging out the bottom somewhere in the middle, for the next step you'll need some extra hands, put the whole(rubber stainless & glass) set up on the cab in place, with a can of windshield cleaner spray around the starting egde. with one person on the inside & one on the outside slowly pull rope so the lip starts rolling over the cab lip. the person on the outside needs to make sure there is enough pressure so it dosen't pop back out. Just keep working at it until the windshield is all in the lip. Be in a good mood when you get started & take your time. Hope this helps. If in doubt spend a few dollars & have a professional install it. Later
