Jimmy... (cab truck will probably happen so far in the future - I'm certainly not saying you're lazy, it just happens, ask me how I know- that anything I suggest will be "old school" by that time...)
Just a suggestion... seems more contemporary than radius arms (but I always think *Bronco* {no offense Danny/Pete} when I think Radius Arms... not to mention leafs, but the simplicity of leafs is nice) and yet still friendly to highsteer and a steering gearbox for streetability-ish...
I'm currently trying to shove 40lbs worth of engine, (beefy) structure, exhaust, driveshaft and 4-links in a 5lbs space under the 5.0L...
...while getting perfect 4-link numbers...
