Don, I am so disappointed. Not one pet picture since post 26. And that wasn't even a real pet, just one of your many friends. Anyway, a real question. As I have not ever built one from the ground up and want to do one someday (I have started getting the parts together that I have never needed before). where did the kingpin angle figure of about a 6-7 degrees layback come from and why? Do you already have the tire diameter and center point heights calculated that you are using at this point of the build? I guess I'm asking some of this because I wanted to know how much I need decided before I start cutting into the 2x4 3/8 thick ? does this play into the four link set up? Last question about the four link, how is it hidden? Are you going to run fenders up front?
