air bag nylon line routing into and out of cab

[sparks427]

I'm going to be doing a manual bag setup on my truck (71 c10) in the weeks to come, bags and brackets are on their way as I type this. My question is to you guys who have done that manual setup, how did you route the nylon line? I was going to do copper but did some reading about some of the troubles with it and decided against that. So I'm going to keep it simple. Any and all info is appreciated! Thanks guys. And yes I did search and have been searching for a long time with no positive results.
