I haven't cut my top deck, and haven't seen one that has been done. I therefore don't want to give wrong advise. I have already sent a PM to Taz earlier telling him to ask Mossy who has experimented with the top deck, as he is the best person to comment.
And what use is your link Mr Wonderful? It's just a link to the car spec? I guess you didn't understand his question?
Taz - read this thread as i told you to earlier before you started another thread. The top deck is discussed here.
