That'll be a Dart 270, which was the high trim level (Dart 170 was the low level, and Dart GT was the premium level). Note the "170" and "270" trim levels don't imply anything about what engine any given car was built with. All '63 Darts had the 170 Slant-6 as standard equipment, 225 Slant-6 as an option.

Red. "Chrysler red" as sold by Mopar Performance is not a good match, but "International-Harvester Red" as sold by Martin-Senour paints (NAPA, last time I looked) is. See
here.
No. A/C was a dealer-installed option, and it wasn't supposed to be installed on cars with the 170 (225, yes). So since I see a light coating of Turquoise I am going to start out thinking this is not the original engine. Time to look at some numbers on the block.
Yes, 3-on-the-tree. The dashboard looked the same except the left cover plate had no pushbutton holes.
Yes, on the left inner fender.
