Tim, the 2nd half of the PDF for 55 2nd covers all the [55.1?] AD specs, that is, it's both years combined .... and still, the number 243 is listed [under both series info] as an RPO, not a paint code per se, although I guess your Salesmens Data book expands on that with the G, but as I pointed out, all paint chip sheets show TF colors as 700 numbers, which is the other number on Franks truck, and his data plate shows "trim" and "paint" numbers [which doesn't match Carters repros for 55 OR 56/7] I'd suspect the data plates were not uniform across plants, and not as reproduced, and that some published info in that "turbulent time" just repeated the previous years details
does the Salesmens book list trim codes?
