I need some quick advice if possible. Is there a known procedure to removing the backbox on a Data East Version 3 DMD game for loading in a small vehicle? According to the below photo there is a vertical bolt inside the bottom of the backbox on each side attaching it to the hinges. Or would it be more preferable to remove the hinges from the cabinet? I'd say removing the backbox from the hinges would be easier. What size ratchet/socket would be needed for the backbox/hinge bolts?
