70 Gold Duster Without Vinyl Roof - Possible ??

The Gold Duster was a mid-year 1970 model, but a vinyl top was not part of the package.

See the ad for them at http://www.hamtramck-historical.com/images/vintage-advertising/1970/1970 Gold Duster ad.jpg

If you wanted one, it could have been had as an extra cost option.
