your car but...before you make such a decision, let me tell you about mine. I have to start with fact of common knowledge, Plastic gets brittle with age. The guide, made of plastic will break in half right through the drilled hole. This is what happened while original owner had my car. upper guide broke, upper corner of glass dropped out of the channel. I don't know if the wear in door hinges was a factor in all this. Anyway...
So, a helping hand to roll the drivers glass up down, no big deal for him.
Every time he closed the drivers door the stainless on the rear edge of that door glass scared the stainless on the quarter glass. When I bought the car, it looked awful, kind of like someone had tried to break in.
Of all the repair work involved, correcting the quarter glass damage was the most difficult part.
