I see what you are saying, but it just stands to reason that if the fronts of the arms must remain parallel so your tires are both steering the same axact angle, then the rears must too, does that make sense? That would mean that throughout the movement of the tie rods, as one increased it's arc, the other would simultaneously decrease it's arc at the same rate which I would think would balance out. The other issues I am having are that I was reading over at pirate that people have basically said this won't work in theory or on paper, but there are people running it problem free. It's very confusing trying to sort through all the contradictory information. I think I may make a model out of PVC and some plywood to real world test this. Also, I wanted to ask if you saw an incredibly big difference between the more desirable and most desirable mounting methods. They look about the same except the ram is deflected to the right in one and centered in the other. Another note is that most hydro steer arms I have heard of mount up on 8 or 9 inch centers. I dont know if that matters, but there you go, they did mention proper Ackerman angle as the reason for that though. Also the rams I have been looking at are typically 8" throws for ~40 degree steering and
10" for 50 degree if you get the U joints machined. Here's also the prints for an example 8" ram(not the one I'm using, but close enough)





The pivot centers of the kingpins are approximately 53.5" as I assume the forward tierod will be as well.. The tierods for the ram are obviously whatever lengths they need to be to set up properly. Hope this helps, I'm crossing my fingers.
