Ah, I think Glen was kidding......
Not at all! There is a 1" gap on a 72 between the bottom of the the embossed letters and the top of the coin door.
Metal has been rolled there and will be ideal to weld onto without warpage. The entire door is solid across and should absorb the heat from a continuious weld easily.
But the body will be more difficult as a continuous weld heats and contracts the sheet metal way too much. So I would make my cut where I planned on breaking the red and white colors. There multiple spotwelds could be used to tack sheetmetal together, this line will be covered by a chrome divider strip when done. Hinges need to be moved.
If I owned a welding shop, I would try it, but farming it out could get cost prohibitive.
