71 Duster 340 Wedge

Thank you all for your greetings. I am glad to be here. I need some help with something's. The Duster had been redone when I got it. I found that some little lights don't work. Have fixed some, but I have not light in the gear selector, so I can not see what gear I am in when driving at night. How do I go about getting to this bulb to see if I need to put another one in there? Also, have no light in the ignition switch. I put a new in there but it still does not work. Suggestions what to do or try would greatly appreciated. Thank you.
