The smittybilt product is completely different. It only works when your top is removed and looks like a general pain in the ass. The windows here simply replace your soft top windows. It's a lot easier and pretty cool looking, IMO. There is a pic of a 2 door on the first post but no where to order it. Maybe try calling the guy. He doesn't appear to go online much. Great idea, just needs more polishing in the advertising/webpage area.
