1965 Plymouth valiant defroster hose routing

We're routing defroster hoses, and the passenger side is pretty self explanatory.

It's the driver side that we're having trouble with.

It's really really tight back there. Lol.

It looks like it comes down on top of the back of the ashtray to avoid the wiper linkage……barely.

And it just barely squeezes between the radio and the ignition switch/wiring harness.

Is this where the factory routed the driver side heater hose?

Thanks. Eric
