I can understand completely, dusters are my favorite cars. I particularly like the 73-6 style of duster but they are all great. I was on the hunt for a 74 duster when I got a tip about one for sale. When I got there, i saw a sport roof in the brush but it turned out to be my 72 demon.
Never found a 74 duster but the demon has the same basic shape, so I love them all. :)
