A-body help needed for my 65 Barracuda

I drove my car downtown and was leaving work. As I backed out of my space in the parking deck my brakes failed, engine stalled, and I started rolling backwards down the incline towards the bottom of the ramp. I was unable to stop the car (pulled emergency brake and tried to throw car into Park with no effect. I hit the wall at the bottom of the hill at about 35 mph. Pics attached...the damage is bad and I am still in shock but I will get her back to where she was.

The good news is no one was hurt. I didn't hit any of the dozens of cars on the way down the hill. And lastly, me and the car did not go through the retaining wall and fall 5 stories to the ground.

I had this car for 2 months and had just taken 2nd place at a local car show. The previous owner spent 17 years restoring this car to near factory original and I feel like I have ruined a piece of history.

I need parts for the car. As of now I know I need the following:
  1. rear bumper
  2. both complete rear tail lights units
  3. both rear quarter panels
  4. new steering wheel (bent completely out of shape when i hit holding onto it)
  5. possible new trunk lid
Will find out more this week once it gets on a lift and is inspected but she wil lbe out of commission for at least 2 months or more. PM me with information.
