The Duster I did for my son is a 75 360 car but no sunroof. My buddy has a 75 360 Duster with the Space Duster option package with the sunroof. I believe his dad did some digging years ago and I want to say it was something like 25 360 cars with the sunroof...pic of his car. He is a member on here but I dont think he has actually logged in for a long time.
Could you message me his name ?
