Ed,

The glass guys will know more about this but I think I would try to have it fixed. I had a tiny chip in one of my cars with a top once and it was ok until a cold day when I turned the heater on. I was driving down the highway and heard a loud snap and there was a crack from the top where the little chip had been all the way down and across the driver's side of the windshield and I had to have it replaced. This wasn't on a Cobra, but I would think the glass might react the same way to heat and cold changes. Also if your car rides a little rough that is something else to consider. Just my guess.
