Thanks RT can you be a little more specific as to where this allen screw is located?There is also a 3/16"(I think....) allen in the hole behind the little hole with the rubber grommet in the door frame that needs to come out. Then it should pull kinda straight up and out. Be careful not to damage the front plastic slide strip on the window that slides into the vent window track on the front of the door glass. When I did mine, I had the door glass loose as well so it gave me some room to wiggle. I can't wait to assemble it all next year when I half *** forget where it all goes and then try to get it all back in haha!
