Found a second buildsheet in my car??

I know i know, i could have used the search button.. I did! And i didnt find too much help, im starting to wonder if my car was built from a whole lotta different parts? The fenders have extra holes above the "swinger" script what went there?im pretty sure its the "Dart" script but not a 100% ?? Its a 72 dart swinger by the way. The axle code is d51 and the next box over says "d8 size" with a "1" in the box. What's the difference between the box that says "udf color-gB5", "paint style v01", "body paint-hB1" and im guessing "roof-paint/style top- v1w is a vinyl top, but what color would that be? And the next box which is "stripe-v5x" what the heck is that lol ? Now i got the car in piece's for 600 bucks. So i think i did good lol and nothing was on everything was bare,and/or spare. Except for seats and a rotten carpet. Anyone with any help on my questions i greatly appreciate it thanks.
