Thanks arpad_m. I managed to get it off without scratching anything. The page you provided was very valuable. One thing that is missed on the page is the part will slide forward about 1/2 inch once you get the upper and end retainers off. This allows most of the bottom retainers to unlock and get close to coming out. A few will need a little help. I managed to do it by myself but I have a lift that made it easier. I would recommend two people do this job to prevent damage.
Where did you get the manual? That is a handy thing to have.
