Neather the Team Buick Reference nor Cars & Parts ID Numbers Catalog shows the seven digit number located on the body number plate between the line : General Motors Corporation and the line containing the style number and the body number . Does any one know what these numbers are and how to decipher them ?
Also were do you find the translation for the accessory codes listed on the plate ?
One of the codes on the body tag is the Fisher body number. It does not relate to any other code, and is just a number assigned to the body. This may be what you are talking about. I think we could decode your tag if you were to attach a picture of it or recreate it here.
