Tv Mount in CRT TV cabinet space

OK, this one might be a bit tough. I notice that the old tv has speakers on each side, which make it a bit wider than the screen. Will the new one fit between the two cabinet doors on each side?? If you haven't got it yet, look for one with the narrowest edges around the outside. That way you get the most screen for the width. I am thinking about building some support structure inside the cabinet, then using a pull-out type wall mount. Velcro strap to go across the front when traveling. Are you game for a little cabinet remodeling to set the new one flush?? Due to the weight of the old tv, there should be some solid structure in the current cabinet to support it. See what is there.
