Still looking for brake lights and turn signals... HELP!

I am having almost the same type of problem on my 70 Duster 340

I have all working lites except for no parking lites. I changed the headlight switch and turn signal switch but still no parking lites, I have headlites though. I wish I could help you out I will let you know if I get mine going. Anybody with any more things I could check? :cry:
