That definitely looks like a widely available aftermarket hose. It took well over 20 years to finally find a correct hose for my 68.Does anyone have a picture of how the factory routed the power steering hose?
It's a really long hose that has a few possible ways it can run.
66-7 Coronet and Charger should be the same.
I didn't see anything in the FSM or online.
Here is what I have.
