ok here is a breakdown of the high impact color production numbers by model. it is only the the percentages. these percentages will need to be divided into the car production totals to get the actual number of cars made with the paint color. these numbers are for 1970-1973 , sorry no numbers for 1969 models........
1970 dart 340: plum crazy=14% , sublime=6.7% , go mango=6.8% , hemi orange=7.1% , lemon twist=10.0% , green go=0.4% , panther pink=0.6%

1970 duster 340: plum crazy=3.2% , sublime=5.7% , go mango=5.7% , hemi orange=8.1% , lemon twist=11.3% , green go=1.7% , panther pink=1.9%
1970 duster: plum crazy=3.2% , sublime=2.2% , go mango=1.8% , hemi orange=1.4% , lemon twist=1.4% , green go=0.7% , panther pink=0.7%

1971 demon 340: plum crazy=9.5% , hemi orange=16.7% , lemon twist=0.1% , green go=4.2% , citron yella=7.1% , bahama yellow=8.9%
1971 demon: ? unknown at this time * percentages may be included with 1971 dart swinger #'s or combined with the demon 340 #'s*

1973 dart sport 340: lemon twist=10.5%
1973 dart sport: ? unknown at this time * percentages may be included with 1973 dart swinger #'s or combined with the dart sport 340 #'s*
1973 duster 340: lemon twist=9.7%
1973 duster: lemon twist=7.5%
* my guess on the non 340 model demons, and dart sport's are the numbers are combined with the 340 models. seeing as the percentages are higher on the 340 models and the production on these cars are fewer that the 340 plymouths models. could be wrong though. i will update if i find the correct breakdown on these models........
