Well I finally got it installed. I ended up mounting it on the inside of the frame rail fwd of the cross support brace that runs across the back of the trans. I had to slide in a spacer plate between the frame and the airdog bracket(1/4" steel plate) to give the filters some clearance from the torque bar(I guess that's what you call it).Worked out pretty well,puts in the same vicinity as the oil and tranny filter and it's still inside the frame rail which I wanted. It's pretty close to being right under the driver seat and I was concerned about hearing it.But you can faintly hear it with the eng off,running it's not even noticeable.The only thing I needed to get was some extra fuel line because it's mounted a little further fwd than the directions call out.I'll try to get some pics up soon.
