1965 Dodge Dart Charger

'65 FPC shows the following:

2495 878 mirror package, left remote
2486 371 control, remote control mirror
6025 708 Nut, rear view mirror control, attaching

I'm assuming the 2nd number is included with the 1st. Maybe the 3rd is as well, but the book isn't clear. You may need to add a spacer ring between the control body and the door metal so as to 'shorten' the threads protruding into the driver's compartment and allow the cap nut to tighten with no gap.

no one would ever see it!

When, in the history of this project, has that ever stopped you?
