open questions:
Why does this have an A instead of AB engine code?
What code is for the pushbutton 904?
I didn't think 64 Darts could have power windows, what's that H - 5?
LIkewise tach on a 64 Dart? Never heard of that. What's T - 8?
What code is for the power steering?
Guessing K - 6 is the power convertible top since K is used for power tailgates on wagons.
The biggest open questions are about color. What color were the top and GT stripe? Guessing Everything black except the stripe was white.
