Yes I am the owner of HS30 00016 and the seat belts are branded 1969. Many early 240z's came to Australia with no indicators in the guards. I believe 00016 came to Australia and than traveled to some pacific islands and possibly even PNG before ending up in New Zealand were I purchased it in 1994 (I think) This car has now been back in Australia since 1998 and is now under going a major rebuild.
