Agreed, 100%! I'm not trying to denigrate anyone's pride and joy. Just chasing down an odd notation about the special trim package and how Dodge made some of the vehicles back in the day.
And in the process come across some very cool vehicles such as your own. It is the first 274-4 270 I can recall seeing and having a manual trans even cooler. The original owner as well? Wild!
I have edited the post with the scans from the Data Book, it even contradicts itself showing standard on a few pages and "manual outside mirror" on another page.
