Parking Lamp / Turn Signal Questions - 65 GMC 1000

[Praxiss454]

Howdy folks,

I have some electrical gremlins (and some newbie questions) and I'm hoping someone can help shed some light on things.

1. Does my 1965 GMC 1000 have front turn signals? Seems like the yellow lens parking lamps should function as turn signals. Mine don't currently.

2. If the answer to #1 is "yes", what is the likely culprit? Here are the symptoms:
-Rear turn signals work
-I don't see any turn signal indicator lights flashing on the dash
-My parking lamps do not function w/ the headlight switch pulled out half way
-My parking lamps do not function as turn signals

3. One of my parking lamp lenses had screws holding it in place. I was able to pop that one out and swap bulbs. But the other lens looks like it has rivets or metal posts. How do I take that cover off to replace the bulb?

Thanks!
