Just thought I would share the response sent from Ben. No luck unfortunately:(

Thank you for visiting HHS and for your enquiry.

Unfortunately, in this instance this HZ Holden - L462109 - is not included in the HZ Holden Vehicle Master Listings we currently have. The reason for this is due to the implementation of the new One Line Reporting system from July 1978. GM-H outsourced all warranty reporting activity from this time. It was cheaper and easier to do it this way, apparently. There was a big song and dance about it at the time. Sadly, all connection was lost many years ago and we are in the process of currently trying to establish if the data still exists in a usable form. We have our fingers crossed on that front!

Having said that, we can decode the vehicle for you.

The ID particulars belong together as a 'set'. That is a real bonus for starters. The chassis number stamped in the frame - CHZ67286A - matching exactly with the number appearing on the ADR Safety Compliance plate confirms the two belong together. This could be a Sandman, however without the build records entry we are not able to confirm it.

L462109 was originally built at the Elizabeth, Adelaide plant during the final week of September 1979 as a Holden panel van. The original colour was Malachite metallic ('1954' on the TRIM line of the Body ID plate) with a Buckskin vinyl interior trim ('63C'). The original mechanical build configuration was for the optional 5.0 litre V8 engine, optional 4-speed hi-performance manual transmission and 3.36:1 rear axle.

The chassis number - CHZ67286A - reveals this was HZ Holden #67,286 produced at the Adelaide plant. The seating capacity of '2' appearing on the ADR plate confirms optional bucket seats.

The engine serial number - ZT44870 - is in the zone for being the original factory-fitted unit.

It may well be a Sandman (P/O XU3), as the build configuration is suggesting.

Sorry we won't be able to provide a Report for this Holden on this occasion. I hope this is of some use to you.

Kind regards,
Ben.
