I've got 3 Here that are factory Moonroof Cars, (plus I installed a Glass "Pop Out" Sunroof in my '74 Duster-Twister)
A 1973 340 / 727 Dart Sport with Factory Moonroof
A 1973 340 / 833 Dart Sport with "Conver-Triple" Package (Fold Down Rear Seat, Moonroof)
A 1973 340 / 727 Duster with a Factory Moonroof
All 3 are "H" Code Cars
Plus I have the whole roof (cut at the quarters & A pillars) from a 1971 Duster/Demon with the very rare V3X "Canvas" Roof option.
Here's the '73 Duster, I did some "modifications" to the car...
And my dad did some modifications to it too, back when he owned it.
The Duster is an H Code 340 Car, Factory A/C, Moonroof, Power Steering, Sway Bar, Light Package, Bucket Seats/Console (seats have been replaced, console was replaced with an E-Body Console), etc. Swapping the 727 for an A833 soon
