Thanks alot you guys. You were right, my 4x4 converted '66 was way off on caster (it was set at about -10 degrees!). No wonder it was all over the road. The fix was to mount the solid spring pertch in the front and the 'live' shackle in the back by using one from a mid 80s ford ranger. This setup rotated the axle housing back enough to have a positive caster of 5 degrees and no driveshaft bind. Apparantly Sky Jacker lift springs concern themselves more with the lift than the axle orientation.
Now to correct for bump steer, do you reccommend a raised steering block to get the steering arm parallel or to go to a crossover steering link setup??

im no expert, but i would think the shorter the steering arm the stronger. so a raised steering block to put it all level would be best over the cross over. or, have you tryed a d400-600 steering arm? they are about 2-3 inches longer from the box to the end then the 1-200's arms are. might just solve your problem right there by dropping the steering arm rather then raising the axle link

Glad you got that fixed. Might be a little unfair to blame Highjacker since I think you have a later axle? Would be pretty hard for them to know exactly what the rig would require without some input from the owner.
I am sure Trey is right about the shorter arm being stronger and the bigger D steering arm might be a good bet. They may not work though since the cross shaft is likely much larger on the bigger rigs and would not fit yours. Crossover steering seems the route most guys go to eliminate bump steer. If you do have a later open knuckle front axle you can probably find a kit to make it crossover through one of the 4x shops.

i think they are the same steering boxs on all of them, so the arm should be the same in all but length my service manual shows the same box specs for d100-600 on saginaws.
