Rhino,
"Where was the factory antenna mounted on a 78 LPB? It looks like this truck had one mounted on the passenger cowl area and possibly on the driver's side near the kick vent."
Kooooool. That way the previous owner could broadcast his own brand of music on one side of the truck, and receive his own radio station on the other!!
But seriously, I have been told by those who know, that the antenna location depended on the way the truck was originally configured as ordered from the factory. Those with radios delivered in them from the factory-- got one side; those with dealer installed radios could go anywhere, some more forward on a side kick panel. Without the actual build-sheet for your truck, it is hard to say if yours was a dealer or a factory installed radio setup. Maybe someone out there has a build sheet from the factory for their setup, and then we will definitively know.
I have noticed on these as well as on other vehicles, in RHD countries, where the driver is on the side opposite to ours, frequently drivers like their antenna close by, so they can fiddle with it outside the window while they are driving, and aren't bothered by it appearing in their immediate field of view. The antenna question is sorta like the age-old dilemma of which side should get the gas filler neck!!
On a similar note, I have a late model 45 with dual radio speakers that came factory mounted on welded captive-nut tabs above each kick vent, as opposed to the standard single radio speaker slung under the glove box. Weird, but shows where Toyota was headed with more modern audio equipment.
