@SM3570, I did look for a build sheet, and did remove carpet, rear seat and door panels for a "look-see". None, but I wasn't surprised, since the prior owner had some interior work done. As far as the "codes," they are still on the underlying build tag, ie: the "G" Code Boss 302, "5" toploader, as well as the metal tags on the 9 inch "N" case, with Daytona pinion support.
There's a heck of a lot more to this story. I actually have 6 different Emminger sheets for this car, all different, and at least 3 different VIN's, all ending in "100053." If you saw that link I posted earlier to Emminger's notes on the first 100 Mustangs for 1971, you will see my number is circled with a note. At one point, Ford invoiced the car as 1F05R100053 (the earliest Boss 351.) But on it's birthday, it was built and tagged as 1F02G100053 (Boss 302)
