I remember this owner and his car, from back in that time period. I agreethat this is likely NOT a v24 car; But having said that - the Winchester Gray could make a cool '71 340 Duster and rare color at that!
Somehow I vaguely recall that the owner finally encountered a health issue and he may now be deceased, but it's speculation. I thought that this car was either sold on Moparts or was talked about there, and perhaps the car was sold-even on Ebay.
The spoiler is wrong but I'd like to see the fender tag.
Even still- a 1971 Duster 340 4 speed with chrome sport mirrors in Winchester Gray is a cool car!
