Is that one inch with taking the door off? The reason I ask is that you probably have more than one inch available, depending on how involved you want to get. You can easily take the door off, but if you really want to have this thing in the room you had planned to put it in, you'll probably have the room you need by taking off the jamb and the casing around the opening. The casing is usually 1/2" itself, which would give you the room, and the strip the door would close against would give you another 1/4". If you lived closer, I'd come do it for ya, but it's really not that hard to do yourself, just use a putty knife, hammer, and patience. Go slow and don't yank, just gently pry. If it don't come loose, get a bigger/thicker putty knive (read: screwdriver or prybar) and gently give it a pry until the nails loosen up. If you mark 'em right, you can probably use the same nail holes, but I'd use a bit thicker nail.
If all else fails, a Sawzall can be your friend!

If you could send me your pics to use2b_chzhdz AT hotmail DOT com, I'd appreciate it.
