So they are supposed to be THE quality piece. What were your experiences? The quality of the materials looks great. Here's the but- The outside edge (there is a groove in the middle of the horizontal surface) nerest the glass is wider that the stock part that came off. this puts more pressure on the glass and bows the rubber up more also causing a bit more friction when rolling the window down. Also the screw hole spacing leaves a little to be desired. The factory skipped every other screw. If you do that with these it is horribly bowed in both the vertical and horizontal planes. If you put in all the screws (#6x1/8 black treated pan heads that I have yet to find replacements for) it helps but is still not smooth like the factory look. Some holes, even the elongated ones, are not in the right places. I can probably further elongate them, but come on. Others appear to be too high or too low. Due to the small size, the risk of making them too large is there if I try to fix the location by enlarging them. Not sure there is any other way, though. If I can get them installed 'correctly", I think they will look good. Middle pic is all screw used. Bottom pic is factory screw install. Pics really don't capture the up and down issues.
