So do I have a rare 71 duster 340?

Heres the production numbers i found for 340 dusters..

1970..24,817
1971..12,886
1972..15,681
1973..15,731...

never knew the '71's were that low in production..'70-'71's still my favorite years:D:D

The usual statistic on Muscle cars of the era are approximately 10-15% survived. That doesn't leave a lot of 71 Duster 340s, especially ones that aren't hacked into race cars, etc. I consider them somewhat rare, not one of nine type, but still rare.
