My new 71 Dart and the issues I am finding. Help needed please

I just bought this 1971 Dart and feel I got a good deal. However, I need help figuring out what to do. I have found issues with the instrument panel - bouncing speedo, fuel gauge dead, no lights, no radio, no cigarette lighter, no wiper/washer, blinker that wont stay on when turning right, no horn, no heat, fan, or AC.
It has a 318 and had factory air.
I had a 76 dart that I had some instrument panel troubles with, and was able to remove, repair it. I also replaced the radio. It had no factory air to contend with.

Since that time, I had neck surgery and cant bend like I used to. How do I approach this?
I need working instruments, lights, wipers and a radio. The HVAC i can get a mechanic on.
I know there are a lot of you who know how to do this. Can you advise me please?
