Heater hose routing 65 "gt" 273

Depends on if you had AC. Below is a photo I socked away of someone's 65 Dart 273 that looks like they are trying to be original (factory AC & booster). Still, might be 50/50 on the heater hose order at the firewall (heater works either way). Check the factory manual for drawings, and might depend on whether Billy or Jimmy installed the heater hoses that shift at the factory.
