A fair amount of the original factory data on 67 Plymouths was lost in a fire long ago, so unfortunately there are no really good records concerning break downs like you are seeking. There are people who keep track of what exists now and I can tell you, the numbers are small. Due to so many possible option combos nearly all of them are "One of One". How is yours equipped?

Here are some generally correct numbers. These should be considered "close"- there are probably some variances.
