1975 Duster 360 production numbers?

A buddy of mine had one with those options and more, it had 2 full fender tags. It seems to me he got a number around 25 or 35 360 cars with fold down seat and sunroof options. Not real sure how accurate that number is. He sold it last year after having it for 30 years. My 75 360 car has very few options. Here are picture of his and then mine.

Is that not a 74 stripe on these 2 cars? Looks like a stripe from Challengergary. Thanks. Kim
