Just to be clear, and not to confuse anyone by the above comments, this is NOT a Sandman. 2 things on the tags say its not, 3 seater and no XX7 stamped (it is Brisbane built). The 'Monday cars' I have seen referred to have only 1 mistake (not 2) or are corrected at the factory (eg 3 seater stamped over by 2). Further if console brackets are spot welded, this is not the way the factory did it.

I am sure something has been lost in translation from Byron if he did say it was, or if he has it recorded as a Sandman perhaps a previous owner mislead him about the tag info/console mounts.

As others have said Holden Historic services can answer these questions definitely for $90 if owner is still in any doubt. Cheap for peace of mind.
