Product review (3 stars): Cords good, pulleys bad
I used the cords and they worked like a charm. They were an inch shorter than stock, but didn't present a problem. When I tried to install the plastic brackets, the terrible noise when opening and closing continued. The original brackets and the new cords are working silently so far, a couple weeks so far. So this is a fix, but not how the product intended. Might as well just sell the cords.
