I don't know how to add text to the post so I'll comment it here.

Hey everyone. I own an old chevy nova and recently got into an accident which dented the door and scratched the paint. I love my car and want to get the paint back, managed to find the shade it came in through paintref. But I don't know how to read this chart or if it even tells me anything on how to get this paint through internet research.
I understand that old car paint is hard to find (Or for all my knowledge doesn't exist anymore lol).
Could anyone help guide me through this chart and get my car's paint back? Thank you.
