Something to consider, not all game specific parts for RS have been remade, not just the plastics.
There is NO difference in exported or domestic games except transformer settings and coin doors.
This enthusiast fallacy came of the reimport era before 2005, based on resellers trying to pitch higher prices for US games, or even hide the fact they were exported to increase sales.
"Good deals" on this title are fleeting today, because potential owners don't know what is missing and find out late the game already had been stripped. There are a number of unique PCBs as well, some are repairable, some are difficult, based on parts or experience.
Know this title well, and it's associated Achilles heels.
My company is piecing together another working version from two games, due to this exact problem and are using my experience based on ownership/restoration of a sample game for nearly 20 years.
