I'll second the reccomnedation for Raybo. Great work, great value and great service.
What shape is your windshield in now? I would suggest contacting these guys or having whoever does the work contact them.

A full replacement is in the $2-$3k range. but they should be able to provide gaskets and replacement glass should you prefer to restore what you have. If you can swing it, I'd go for the replacement. Mine was repainted shortly before I bought it and it hasn't held up well.
