1971 duster
I have not done Any color drawings for 71 yet. I can or maybe able to download an original 71 Shop manual and assist if still needed.
Lots of DR. appointments the rest of the week but willing to find some time between them. One thing for sure is a need to understand all the options on ones "Your" vehicle if available to locate the exact diagrams in play.
They "Chrysler/Plymouth" original diagrams are usually all there though, and reading between the lines is required! JMO!
