Hi, got a wierd one for you all

I just got this truck, it's a 61 Chevy 1/2 ton, and I am trying to sort out the glitches so it'll pass a safety inspection.
The right signal works, left one doesn't. The right one also keeps blinking after it's been shut off, but it will shut off if I move the lever to where it should be blinking left, and then back to the middle. Also, when I pull the light switch out to only turn on the park lights, the tailights come on, but the park lights (signal lights) up front don't come on. Also, the green signal indicator on the dash comes on for the right signal, but stays steady. What in the world is going on here? My guess is that I need a new turn signal switch in the column and a new light switch. Any other ideas?
