I have done some measuring, at least the best I can with the window glass still in place - they measure close to the same between the 2000 and the 1996 model. Has anyone tried to install a slider from an older truck ('96) into the newer model, and been successful? I can see the newer glass is glued in, but I wonder if the openings are the same size & shape, and once the glue is cleaned off, if the one with the soft rubber will fit in it's place.
