When building the Scrambler, I needed to have a windshield swapped. I had the old one, the glass was good, but pitted. I also had another frame, had to weld it up to patch the holes, but hey, it was a frame. Brought both to a windshield shop to have them swapped. The guy swapping them slipped and broke the windshield, cost me $35 for a new one, just the price of the glass. When it leaked later, mostly due to the welding I did, he sealed it for nothing, doesn't leak a drop now. I have seen many people try to swap their own, some with success, some without, personally I would let another person do it. He was able to use the same gasket, but had another on hand in case he couldn't. A note to remember, don't use silicone to seal the windshield, it doesn't come off and makes changing the glass almost impossible. The glass tech told me this, he said if I needed to seal it to get some glass sealer from a windshield repair shop for about $5. It will come off and they can change it later.
