Did you catch that the Space Duster package C73 is a requirement for the A63 interior package.

Not sure that applies to the Dart Hang 10, even thou it has the fold down seat. C73 is not showing on the fender tag, have the build sheet, but is not in super great shape.. here is the seat for the hang 10.
