I'm working on the car this weekend and will snap some. Do you need pics of the valve set-up or the placement of the two coolers? I'll post both.
Regarding the lines, i used to slightly flare the ends of the cooler lines to allow the robber hose to hang onto the ends better, but I have since switched to a compression fitting style of end with a hose barb on it.
Be sure to tighten and loosen the compression fitting end of it several times to allow it to seat onto the steel line. I suspect stainless steel lines would even require more of this process to get them to seal reliably.
