The Duster was available with a sunroof and fold down rear seat called the space duster, They are not Hang 10s though, Hang 10s were only Dart Sports and they didnt all have sunroofs.
100% correct Adam.
The Hang 10 Dart Sport will also have an A63 code on the fender tag and broadcast sheet. 3,259 were produced for U.S. in '74 (all engines). They're pretty rare.
BTW, i have a car identical to the one for sale, '74, /6, A63. It's in rough but restorable shape, they could be sisters other than condition.
Here's a free bump for a nice car!
