Buickzz van was Acacia Ridge built and Acacia Ridge is notorious for build stuff ups from not stamping plates correctly to installing parts that shouldn't be on a particular model. My old man worked on the production line at Acacia Ridge during 1970-1971 and told me many stories of his antics there from assembling XU1's to bets with other line workers to assemble cars with upgraded parts.... forgetting to put a GTS speedo in a Sandman would be nothing new. Production broadcast sheets were not supposed to be left in the vehicles but they have been found under dashpads and floor coverings or stuffed inside seats. It was a running joke to see what they could slip past QA.
Production line workers could have been so conditioned to only installing GTS speedos in GTS vehicles that when a van or ute came along in 74 that was a Sandman they just put a standard one in it. There are more and more Brisbane built HQ Sandmans being found that don't have XX7 stamped on the plate.
