I managed to break my rear and both side windows on my Leer 100XL topper on my 2003 Dodge Ram 2500 crew cab with 6' 4" bed. I won't get into how I did it, but what led to that result, seemed like a good idea at the time. In any case, I have found I can not buy a new topper for that truck from Leer, I can't buy the side windows (replacements for the rear seem available) and I cannot find tinted plexiglass in a size that can be cut to fit. First choice is to fix the top I have, but I will buy a brand new one, if it fits and the price is within the realm of reason.
