quality is about the same from one to another. pick a vendor that is easy to work with.
Remove back seat, lower frist, then top, two bolts holding the top/back in place.
Remove window cranks, screws etc., remove side panels, upper and lower portions
Remove interior plastic corner pieces, one on each side, very bottom of window in each corner.
this will allow you to see how the existing package tray is installed.
remove the tape along the front edge where it would meet the top of the seat. This is basically the only thing holding it in place. Before you start pulling, take note of the ears on the ends of the package tray. These fold up behind the sail panels. You can start pulling straight out but you may need to push up in the center, from under to allow yourselve enough room to get the ears released. You could also take a utility knife and cut the ears off. Just take not of how it is installed, B/C installation is reverse.
Becareful, others that have tried this are in the middle of a frame off, because they didn't know when to quit.
