Fender Tag Questions

Y39 is the sales bank code, thus special ordered would mean the entire car! There may be something like a "not recommended" body/interior color, a special ordered exterior paint color, or any other unavailable combination that a dealer could override, such as a Dana in a slant 6 car!! That's a pretty short fender tag, is there a build sheet?? Look under the rear seat buns, they may have the SO written in crayon on the build sheet!!
