‘76 Duster with a 360 and sunroof (not mine)

With my 10 years of research ive only find 5-6 : 1976 360 dusters... 1 had one and it was a silver duster package with all the previous year 75 duster 360 package but was a bit more luxurious , it had a sunroof and 19 options, ive found that around 300ish duster had the 360 in 1976 and around 50 of them were sunroof and 360 equipped . Was a great car and good chances to buy it back , Extremely rare but not valuable !
