1964 Dart 270 Wagon with 170, 3 on the tree and factory dealer installed AC

My '65 wagon is an original 170/3-speed AC car, but most of the AC parts were missing when I bought it. I've always thought it was a strange option for a nearly optionless base wagon, but I got the docs from Chrysler Historical, which agreed with the trim tag.
If it's on the fender tag, then it was factory. First time I've ever heard of such. That's pretty interesting.
