My stand (generic for a Toshiba) has a piece of glass on top that adds 3/4". There are also little rubber feet that add 1/2" Are there these sorts of things where you can gain an easy inch. Shaving an inch off a flat board is nearly impossible.
Option 4, shave an inch off the fireplace. Is there a trim piece that can be removed?
Option 5, get a different stand. BB has dozens of generic models. Pick one that is shorter.
