1964 Imperial dual AC line routing

Hey I'm putting back in the dual ac system in my car. When I bought it, it had all of the ac lines missing and some of the ac parts too.

I need an idea of how the lines would have gone to the back of the car. Did it go through the cabin? Or run by the frame? It's been a very confusing journey to figure out how to fix the ac!
