Twister Duster

[cdeanz51]

Found the site with a Google search – great site. I have some questions that I thought maybe someone could answer. First off, I really know nothing about Mopars, been a Chevy guy since I was a kid. But I recently found a 1971 Duster Twister (A51) in Bahama Yellow that has caught my eye. It’s had 1 repaint about 15 years ago, has 40k original miles, has a couple little spots bubbling on the rear quarter by the bumper, has had some motor mods, (cam, headers, alum. intake, 4bl) – but it’s the factory 318. The only thing I found after decoding it is that it came with a vinyl top but it's been removed. It has a wing that I’m not sure about – but it looks like it was factory the way the trunk is cut underneath and black paint shot at the bolts. Anyway, ballpark, what are these cars usually worth? Most Dusters I see for sale online say they are regular Dusters with the Twister stripes added...

Any light any of you can shine on this would be greatly appreciated; thank you for your time.
