The windsheild on your 55 2nd is kind of a specialty item since it curves at the edges. I think a glass shop would have to special order it and you may be able to get a better deal buying it on your own after checking all the different vendors. I don't think it hurst to call some of the local glass shops or national chains for the prices of the glass and install separately, but I would be surprised if they can beat the price for just the glass.
