Hey Rog,
Thanks mate. The front didn't come off Popeye otherwise it was an identical job. Although, when I removed the side art from Popeye it became pretty obvious Nintendo painted them and were not finished in Formica like the donkey Kongs & Mario Bros as the paint came off with the side art, so I then had to then fill that bloody great area before it was sprayed.
There was also blue overspray inside the cab from the factory.
