Query: Measure studs spacement first!!!

Big dissapointment! I should have read the reviews more carefully.. I bought this unit because it was recommended as accessory to the Sansumg 42" LCD I was purchasing from Amazon....It turns out this is a very limited mount if you plan to fix it to a dry wall. You cannot slide the bars horizontally and the center of the openings are 31" apart with a little leeway both sides... If the studs are 24" apart, like mine, forget it. What a bummer....Amazon should place a caveat next to its recommendation as accesory.
