70 eec fuel vapor line
 

Hey everybody I need a little help I’ve looked and can find anything similar to my truck? It’s a 70 cst10 with eec tank it has a vent line from the top driver/fill side that runs up the pillar and apparently over to the passenger side. It also has two lines on the passenger side 1 off the tank and 1 comes from the floor up and over and they both run up the passenger cab pillar. My question is how the hell do I remove them? Yes they have a single bolt and clip in both sides I removed but they also have more straps inside up the pillar. There is also that hard line in the roof I can see in through the dome light. I want to replace the rubber lines. When I blow air through I hear it leaking. Is there a tee? And those straps? Remove glass? Any help or info is appreciated thanks 🙏🏼

Here’s a couple pictures and the straps that I can’t figure out or how many there are

I have a CA truck like yours.. I just left them in place. I couldn't see the down side. I suspect they had to be put in before the cab was assembled.
