You'll have to get out the angle finder to determine the angles for caster in the front, and pinion flange in the rear. you can use a protractor combination square with a spirit level to determine the angles. Match the rear drive flanges (diff and transfer) to run parallel, you can do this by loosening the u bolts, titling the pinion up or down and measuring the gap between the spring perch and the spring. Then just get the caster wedges to suit. do the same with the front, only dial in enough caster (check the manual) so it will track well. Caster wedges are pretty easy to make (provided you are good with tools) after not finding any affordable locally, I shaped them with out of some 12x60 flat aluminium bar, a 6 inch power saw, triple cut blade, electric planer and some Mr Sheen for lube to stop the alum galling.
