WIW All Original 74 Duster 360 4 Speed Car?
$18-20K if all solid no bondo and original numbers matching 360 engine/trans to me. If that is not the original color then there is a little knock for that.
1974 HiPo A-Body models are low production numbers.
I paid on the high side for my 1973 but I put it on the lift and inspected all the typical rust prone areas. My Dart Sport 340 was a CA and had previous rust issues and is B5 blue non original color. That was worth more $$$ than the clone 340 1970 Duster next to it with a lot of bondo for the same price. My has the non original engine as well.
