Thanks for the replies guys, I wasn't sure if my question would be seen as this thread was from back in 2009. I posted up again as a new posting, hope this is not a problem. This seems like it is going to be a BIG undertaking and I have no glass experience. I read and reviewed the photos Turbocat posted, it just looks like removing the top deck will give the easiest access but I don't even know if I can still find new top decks. Plus, not even sure how to get the top decks off.

Thanks for the help.
