reelnative, in looking at your pics again, your MC8 appears to be of the last batch that had the square windows front to back, no "D" window behind the driver and no slanted roof brace midships.Find a unit number for your coach, either a plate riveted to the ceiling near the driver or back in the rad fan compartment. I'm doubting it is a '76. That style of side window was just before MC9 production started, 1978 or so.happy coaching!buswarrior
