Sunroof demon

The fender tag says V3X which stands for

V3 = Manual folding sunroof
X = Black in color
Ive owned 2 of these cars 1 was a 72 318 Duster and the other was a 72 340 Demon these sunroofs are ultra rare it is a factory option very seldom ordered because they were expensive. This option was introduced in mid 71 and discontined in mid 72 . The cars were taken off the assembly line and taken to American Sunroof Corp in Detroit where the roofs were custom installed . The sunroof handles on these cars have a VW bug part # and logo as they were originall made by Golde a German sunroof company that ASC bought out they just used the handles that Golde supplied with this roof.
