Jerry 28704 came after 27981. BD39521 is perhaps supplied as a sub. but that is in fact a V 12 E part that began at 1S 50265 and 1S 72257. Earlier V 12 cars used the same part as the late 4.2 cars as that portion of the bonnet was the same. Later V 12 cars had over rider issues hence the part change. Don't blame SNG as I would only make one part also. They need to be massaged but not an issue.
