I hate these windows...I hate these windows...I hate these windows...

My passenger side window jammed, breaking off the plactic tabs that attach the mechanics to the bottom of the window. Not only did the tabs come off the window, but they have broke in 1/2 as well. Does anyone have a fix for this? I tried using epoxy, but the tabs keep breaking. Looks like the adhesive that was on the tabs before was some sort of gasket material...Anyone know what type of adhesive would work best for this application?
