Forget the factory specs, I bet your running radial tires. If so do this: Factory spec for castor is negative to a 1/2* positive. Pull your casters as high as you can, if you can get a full degree or a little better go for it. Keep you castors even left to right. Camber were usually high back then but drop it down no more then 1/4* positive, or if you have rather wide tires go a 1/4* negative. Outside wear is means too much positive camber anyways.
The factory toe range is 1/8-1/4" toe in. If your front end is new and tight, go no more then 1/8" total toe. If you have urethane bushings drop down to 1/16 or less.
You be very happy with theses settings.
