Sambo, yep, getting glass installed is the cheap part. Chromed brass surround & side stanchions(uprights, side posts) is where the money is.

Rebel1 is right on the money, Urethane is much better than using T rubber. Although we owned a Cobra for 6 years without a windscreen breaking and it was mounted with rubber. Headlights were a different story though, went through a few of those.

Haven't heard of notching the glass for side stanchion screws. We've always just made sure the screws don't protrude enough to touch the glass.

There is also different brands of glass and some glass suits particular screens better.

Main cause of windscreen breakages(other than rocks, birds etc) seems to tension on the side stanchions. Make sure there is no tension on the side stanchions from where they mount on the chassis, space/adjust as necessary.

Also don't forget to silcone where the side stanchions protrude through the body to stop water entering as this is a major water leak source.

My brother is the king of getting windscreens replaced. After having no trouble with the first Cobra, this second Cobra will break a windscreen relatively quickly. We were very careful to make sure there was no tension on the side stanchions. Even Urethane did not help. Eventually Don Pilling from Snake Bite helped and it was concluded that the frame was out of shape, as in made incorrectly. The windscreen was not bought from Snake Bite. The frame has only just been replaced, lets hope the breakages stop.
