Stumbled upon some episodes of Adam-12, and about jumped out of my chair when they pulled up in front of the Universal Courthouse Square set, which is the subject of my primary diorama. This is what the building structures looked like in 1955-1957:
And here’s what the same buildings looked like in 1968. The fascias had changed but most of the structures remained intact:
So then I started paying attention and noticed a bunch of 60-66 Chevy trucks in the background. Some are parked, while others are in motion. Here’s what I’ve found so far, in only the first 2 or 3 episodes:
A nearly new short stepside across the street:
A 64-66 long fleetside approaching an intersection:
In the left corner is the headlight of a 1962 pickup that passed the patrol car. The shot flipped back and forth between cameras, only showing the headlight and center of the grille, both through the back window:
Another long white fleetside, and not a very good screen shot:
And yet another long fleetside at the curb:
And finally here’s a panel truck sitting at the curb as they passed by:
I’m hopeful to collect some better screen shots in the next few days. There should be a bunch available since at least half the show was filmed outdoors doing street scenes.
