Front suspension geometry

I have a 1983 F250 with a 460. I installed 31-inch tires in the front and have 33-inch tall tires in the rear. This has put my caster around 0. The truck is extremely twichy and drifts from side to side on the freeway. It does corner extremely well though. The truck is lightened considerably also. It weighs around 4200 lbs. now. I just installed a manual steering box and the steering is about the same. I was thinking on making some custom 4-link radius arms and have them parallel to the ground. My truck sits with a rake. This way I can adjust the caster. What do you guys think?

i personally would run the same size tires all around. smaller tires on the front will lower ur caster. my 66 mustang has 7 degrees of negative caster. talk about unsafe!!
