I've got '98 40th anniversary myself (I think there's 5 or 6 factory Midnight Purple 40th anniversary in oz).
Mine is in Midnight Purple, 4/98 build, I've got rear strut brace, mine is also debadged I reckon I prefer debadged myself.
I don't know which bar came from factory (have been replaced with 400r replica thing and will get original S2 Bumper painted soon).
I know the interior does have 40th anniversary badges, but mine didn't come with standard interior (got S3 GTR Interior).
Cheers
Grant
