Stripping
All cars were striped in variaous colors depending on year and body style. I do not believe that anyone can say that any one striping pattern is correct because all cars where hand striped. I see differenced between the two cars I have. I am documenting the original striping I have left on my car as I restore it. CLICK here to go to the Striping Diagram page.
