Hello, I need help with windshield frame specific dimensions please. I am restoring a '69 BB coupe. I bought the car from someone who started the restoration and quit. The windshield upper frame was deteriorated and repaired but is not aligned properly. The left side is lower than the right side - I don't know which side is correct, if either. If you can possibly help, I'll get more specific with what I need. Thanks in advance.
