Remove the swinging doors. Remove the drawers. Remove the horizontal drawer supports for the right drawers. Cut the right vertical support board (the one that the right swinging door was hinged to) back about halfway (so the back half still supports the cabinet top adequately). The area originally covered by the doors + the area where the right drawers were, would support a 16:9 widescreen nicely. Place one there. Reinstall the top left drawer. Cut the bottom-left drawer support out. Cut the original right swinging drawer down to size and mount it so that it covers the area under the left drawer. Now you have a liquor cabinet, supplies drawer, and a widescreen HDTV in an "authentic" 60's-style cabinet. Nothing of value destroyed. No vintage TV enemies made. No "awkward fit" of a 16:9 into a vintage-CRT hole. A countertop to place your drinks. Whole project takes 1 day. Reasonable results. Disposable when you realize widescreen flat-panels belong on the wall.
