Could this be a sandman - Chassis swap

[ozbox]

Alright, so I have a HZ ute. I pull the chassis out and fit a HQ panelvan chassis. Then I inform rego and they do the appropriate changes. The next month I pull the HZ engine out and fit a HQ engine date stamped and engine numbered appropriately. Inform rego, they make the changes, all good. 2 months later I realise that a canopy on a ute looks crap, so I take my HQ panelvan body and put it in place of the ute body on my "HZ ute" and inform rego. They make the changes, bada bing bada boom , but the identity is still the same and I have the same numberplates . Do I still have a HZ ute?

no..when you pulled the chassis out and changed it rego has to be cancelled in nsw and new rego must be done and you have an hq..once you have done this you can take the ute body off and put a panelvan body on and do a blue slip for weight variation and body style variation and still keep the same rego but your compliance plate with chassis number stating that its a ute will still be displayed to align with the chassis number of the ute...sinbox is a ute legally registered as a panelvan with a matching tag to chassis as a ute..confused..im not.
