Default fuel vapor line install

I recently put the new fuel and return line on the right side of the frame (Classic Tube). The lines were perfect and the pre-bends lined up where they were supposed to. Now I am working on the left side brake line and vapor line and the vapor line is giving me trouble. Does anyone have a picture of the original line routing for 1975? I forgot to take a picture of it and the vapor line seems like it needs a bend at the front to run up near the brake proportioning valve but it is not bent near the front. The AIM is not much help here. The diagram is too fuzzy and doesn't show the exact placement of the vapor line.

Don't know if the line is the same as a 73.
Here's two pictures showing the rubber hose going to the vapor canister with the yellow clamp.

I think that is close. I know the brake distribution block that is bolted to the frame is a little different on the 73 so the brake line with the spring takes a slightly different route at the front end. That sort of confirms what I was thinking that I have to bend the line up over the frame and not run out below the front of the frame towards the front of the car. Thanks for the help.
