Need help removing back closet and tub.

[drowe42]

I'm in need of help. Every thing up to the two rear closets on my 66 Safari is out and stored. We are now stuck on the closet next to the tub. Can not get it to budge. We found the three screws holding the closet molding to the tub. where else should we look? Is there any one who has the magic key? Are we missing steps or not finding screws? Thanks
