The Tahoe/Yukon glass is the same. They had the plastic hinges moulded onto the glass from 2000-early 2005. In 2005, the dropped the moulding around the glass and its just flat with a handle screwed into the glass. The hinges became metal and were glued to the glass. Also, in 2005, the Tahoe/Yukon glass got that plastic applique piece at the top. It is held on there by three screws and 3M tape.
The Escalade glass had the same moulding around the glass until 2005. It then got the metal hinges, etc. The applique that holds the brake light is held on by three screws and 3M tape. Unfortunately, the three holes are in a different spot on the Escalade glass compared to the Tahoe/Yukon glass.
You can always just buy the Escalade applique and brake light and 3M tape it on there. That stuff is really strong and would hold up just fine. You could add as much as you'd like. It is much cheaper than buying the $600 glass/brake light combo!
