When you buy an old Mopar, what’s your “gonna have to do “ list

This might not work for everybody, but here's how I prioritized things:
1. Get a really good stereo and subwoofer.
2. Get a service manual.
3. get exactly one cool -not funny or political, but cool - sticker for the rear end.
4. Make sure you have a hat that matches the car.
5. Start replacing anything made of rubber.
