Re: Window Run Channels
I replaced the driver's side on my daily driven S10 last year with one that I got from JC Whitney. It was torn like yours and the wind noise was getting old. IIRC, it was made by "precision molded parts" (made in Thailand) for around $42 sans S&H and it came in a green bag. My bud who helped me swap it out (he did auto glass for 16 years) groaned when he saw me pull it out of my cab... Said that the non OEM stuff leaves a lot to be desired as far as fit goes. Mine was no exception as it required a decent amount of trimming to get to fit right

. I consider myself to be pretty picky but, I would use it on my syclone if I had to replace it.
Just so you know what you are getting yourself into, you are going to have to pull the glass to replace it

. Here's a write up that I did on window guide replacement
here. Beyond getting the window out, there are sheet metal screws and a steel plate in the window channel that hold it in place. Get those out and it will pull right out. Getting the lower "scraper" out at the bottom of the window can be a royal PITA. The ONLY tool to use removing it is one of those "hooked" hose removal tools. If you decide to cry "uncle" and let someone else do it, be ready to pay well over $100 for something that you can do yourself in little over an hour. HTH's
