That's so true! Around here most of the guys go from vent to one piece windows. I would say most of the conversions go that way. One of my boys did it a few years ago...now, the other just did it. He also had chopped, channeled(sic), cut and diced his truck. He just finished putting in all the window controls with his shortened windows, twice. The first controls were ones made in "the country that shall not be named." the gears stripped out the first few times of use. The next were some old ones that the gears are 64 years old and made in USA! So far, let's say "they continue to hold up to the test of time." New bolt/screw holes and different channel seemed to be the biggest thing.
