We down here in the land of Oz also had locally built utes, which is short for utilities and what you refer to as pickups, however our spares were mounted alongside the front cowl, sometimes recessed into the front guards (fenders) and sometimes covering the drivers side door, as in those days it was illegal to exit any vehicle from the drivers side. In fact cars in the 1950's only had door locks on the passengers side.
Anyway I digress a bit. The point is there are 2 types of 1928 Chev chassis, one for cars and light commercials which used the same chassis (some commercials changed the rear crossmember) and truck chassis, which were heavier duty and longer. These trucks had the spare mounted under the rear, between the chassis rails and were held in by a large U shaped bracket, they also had the small (6 gallon) fuel tank mounted under the front seat. They had no rear cross member at the far back of the chassis as the car chassis did
