Finally, I received my sliders. Now, after cleaning and lubing the tracks with WD-40, I really could use some help on how to install them. I know professional installation is an option; I've already stopped at a very reputable glass shop, but the owner himself was a bit miffed about the installation as he thought the sliders would only be held by urethane and not actually have a physical connection, unlike the OEM U.S. flat glass. Any guidance will be appreciated. Thanks.
