Okay Tim. I didn't know. When I did the mod with the brackets you made which are GREAT, I justlowered the window down far enough to see the plastic tabs which were not broken, took a piece of duct tape on the outside of the glass and over the top of the door to support it, unbolted, flat tip screw stick to bust the tabs, some epoxy in the channel of the new bracket, slipped on the glass, lined up the bolts while epoxy was still wet, removed tape, ran window up and left it for 24 hours. Year, or the best part later, haven't looked back

'bob's your uncle'
