Does anybody know if there's a way to tell if your truck had a slider from the factory? I got a good slider from the junkyard, but it's different than the one that was in my truck, and the gasket I have won't work (when they took the window out at the junkyard, they ruined that gasket). Come to find out, if the good window I have is a factory one, and I need the factory gasket, I'm in rough shape because chrysler discontinued them. Please help!
