75 Duster VIN and code lookup help... pic included

the hang 10 package was a dart sport feature that i think had a moon roof, special paint, and interior. The duster version i think was called the space duster cause it added more cargo space. i do however believe that you could get a dart sport or duster with the fold down seat without getting one of those special packages.... not sure though. as far as the drum brakes go, i believe that around '73 they started doing something with what engine you had decided your brakes. ex, all slant 6 cars had drum brakes (not sure if you had a/c if you had drums or discs though?) all v8 cars had non power front discs and if you had a v8 car with A/C then you had front power discs... once again, i'm not sure about it but hey it's what i've noticed over the years....
