Find a glass shop or someone who installs sliders. Some times you can get the takeout solid glass, which the truck owner does not want, for way cheap. On the sliders, you generally can't buy whats broken. It must be done as an assembly. Just realized its you. On monday, call Marci at Allstar glass in Poway @858-679-9794 [super secret #], tell her that Carl from Ramona said to call her about glass. I used her ONLY for glass work when I managed Ramona Body Shop. They were the only ones that did good work and not leave a butyl rubber mess smeared across the upholstery. Plenty of shops in the county but I can personally vouch for them. 2 thumbs up!
