Yes, they are hell to put in; therefore they suck. I had my driver's side vent window securely clamped and my wife helped by stabilizing the channel so that it would not move as I slowly began tapping the rivots into place. After thirty minutes of tapping, the STEEL (!@#$!@#~!@#@~@!#) rivots didn't have a dent in them. So, then I made two small incisions in each side of the rivot to get them started in rolling on the edges. It worked, but it was still a slow process. Then, an hour later after carefully installing a couple more rivots, I got to my pivot rivot on the glass and wouldn't you know it, the arm snapped. I threw the repair kit in the garbage and now I have a good looking (non pivoting vent window). Thanks "Mr. I-invented-a-stupid-vent-window-repair-kit-man" for wasting my time and money.
