FENDER TAG

I bought my uncles 69 barracuda 383 4spd that he has owned since new. It sat in his driveway for over 37 years before I got it. The hood was partly open for all those years. The left inner fender was so rusty I could pull it off with my hands. The fender tag was gone of course. I couldn't find the build sheet. My question is- is there a place that will make a new fender tag for me with out the build sheet ? Also is there a site I can go on to & get the codes that came on the fender tags ? What all codes came on them ? I know what the car has & doesn't have. I just don't know what all option codes were stamped on the tags. I have heard that you cant get a fender tag made with out a build sheet or get a build sheet made with out a fender tag. Thanks for any help.
