I wish there was a section on the forums where only truthful accurate information could be posted so when people are looking for answers to their build issues they can be steered in the right direction the first time and NOT be misled by other peoples opinions or rumors they repeat. I cant tell you how much time and money I wasted on my build because i listened to people who didnt know what they were talking about.
So, to set the record straight, SATURN GLASS DOES NOT FIT ANY OF THESE BUILDS. It never has, and never will.
For the coupe, like Simple Man said, the OEM Murcielago coupe glass will fit. It'll take some work because of the difference in door sizes between OEM and kit. There is no other donor car glass available that will fit, not even Saturn.
When I did my build, I ordered custom glass to be made to fit. I sold all the extra sets so I dont have any more to offer, but I can check with a friend of mine who ordered custom glass as well, maybe he has some sets left. These are for coupes though, not roadster.
