I am at the point of running air lines before I put the cab on my 41 Chevy truck. I scored a whole bunch of 5/16" steel lines and would love to use them. Although very easy to use, I just don't like (trust) the plastic lines that came with the air bag kit. Anybody done this? This will be a "truck" and used as that, so a little extra durability built in doesn't hurt. What do you think?
