Your photos don't work. here is how both tail/ stop and park/ turn bulbs/ sockets work. You have a ground to the lamp shell, which varies over the years. if there is no ground wire, an actual wire, it is not a bad idea to solder a ground pigtail to the shell and run it to the body. Then you have a "keyed" bulb---look at the pins they are offset, one higher than the other. This forces the bulb to go into the socket only one way. The bulb has two contacts, and two separate filaments, like two bulbs. One contact is dimmer/ less wattage, and is tail lamps in the rear and parking in the front. This contact in fact connects to all four bulbs---both park front and both sides tail all four, and is "tail lamps."
The second contact is a much brighter/ higher wattage filament, and in the rear is the turn and stop, and turn in the front
