Bought my manual (on compact disc) from Dave Graham Auto Literature, Inc. Corona, CA. No contact info. Bet you could find on Google. Original Mopar stuff. Lots of sketches.
I believe that's a body manual - not a service manual. A few weeks ago I asked if there was a 71 service manual here on FABO and the responses were no - just a 70 and 72...
Fortunately, I was able to get most of the info I needed going back and forth between the two of 'em.
