N66 (and later N67) rims and centre console were both optional on any HZ Holden van, but were standard on XX7 and XU3 so a Sandman needs to have them but it doesn't positively identify any van as a Sandman if it has them. The only positive identifier of a 5/78 HZ XU3 is the rear headlining attachment strips, but remember these were also standard on HZ Kingswood vans.
