The third and fourth images are a portion of a 6v Positive ground wiring diagram for a '55 T-bird. As pictured I believe the battery and starter are actually on opposite sides of the car. But other than that should be very similar to what you have regarding the basic wiring.
Hopefully they're not too small.
