Is there anyway to make the rear windows roll all the way down?
If they are not designed to roll all the way down, NO! you need to aquire door guts that allow the window to roll all the way down. this might not be a simple task but it is possible with the right tools and knowledge. And remember if you get the parts from a salavge yard make sure they roll down as far as you like. Also remember to get some door panel clips because you are likely to strip or break the old ones when pulling off the door panel....after a few screws are removed first. The window cannot go all the way down because the door is shaped to accomodate the rear wheel opening. It's designed that way. I've never heard of "door guts".
