I have a new one in a box. Bought at the dealer. $40 shipped, I think I paid $45 for it.
I would get new sunroof side seals before you do the install. I destroyed mine pulling them out on both cars. There are three screws for the slider track on the side, I removed the front ones, and loosened the other two. Seems to give you more room that way. Then, slide the bracket behind the slider track, line up the screw hole and put screws back in. Attaching the plastic to the metal tabs was the pain, took me and my dad leaning on the thing to install. After a year, I took it off to put it on another car, and it fit very well and installed easily. Guess it needed time to conform to the roof curve?
