Super late reply but thanks so much everyone who contributed here - your photos and advice came in super useful. It took 5 months of back and forth emails with several long lulls of not getting any replies, but Yaton came through with the parts! I got all the lock tongs which fit perfectly, an Aero City coin chute which was missing from my cabinet, and even a new Aero City marquee, replacing my suntanned one.
Repaired monitor chassis came in the same day, so hopefully the cabinet will be up and running by the weekend
