I am not going to lie, the glass is a pain to get in, but once in and the front channel is bolted in tracks very smooth and no binding. Initially I had a binding issue, but that was in the sash adjustment. After taking the sash out and adjusting the glass in the sash all was good. I will also say it is not easier on the second window, it averaged 1.5 hours with regulators and adjustments to install each side, regular glass and vent windows are a few minutes job. As I stated before, it is much easier with doors removed as you can get to the lower bottom bolt and the trique latches actually made the upper rear bolt easier to do. I tacked a 1/4-20 nut to backside of the upper track similar to what the factory did to ease installation of the upper track on around the latch. I can go into more detail but it really is a feel your way through it type of install. Still say it is worth it but you will definitely have a time investment.
