well I suppose I'll put what I've done up, still have to build the center mount that will hold the compressors. I did the outer ones for each side, I couldn't come up with a good placement that would keep from running extra wire and line past the notch not something I wanted a big nest of hose and wire running down the frame rail. As it is I will have fuel lines and tail light wiring going back already.
Also all 8 valves will reside between the square stock that holds the air tank, and I will run plumbed like a manifold so there will be 2 1/2" hardlines feeding the valves.
the pics are blury, I keep tweaking the camera but haven't got the solution to why it sucks
notice the slip yoke donor in the back ground
