Help finding fusible link for 75 Duster

Not directly related but I wish people - Rick in this case - would stop calling all black wires negative.
"Notice that the “black” (negative) side of the ammeter was the factory’s choice for accessory current take-off."
The Black Wire connected to the Ammeter is NOT a negative or ground wire!
The Black wire connected to the ammeter is a HOT wire.
