I just recently purchased a 72 Cuda, and the drivers door window wasn't working properly. After going inside the door, I noticed that the two front rollers were not attached to the window. I have all the pieces I need to re-attach the rollers, other than the two spring nuts and the insulators that go between the spring nuts and the glass. Does anyone know the correct part number for these items, or where I may purchase them, or have originals they are willing to sell to me? Thanks in advance for all your help and advice!
