Re: Positive camber... just remove the shims?
 

You're right. There is a formula on the page prior to the chart. Didn't read it thoroughly enough I guess!

However, I'm starting to wonder if I am overthinking all of this. From what I have read both in my manual and online, the caster specifications are from 2.0° to 3.0°. My caster is set to 2.1° on the driver side and 2.6° on the passenger side, which are both within specification. The truck rides very smoothly and doesn't steer too hard at all either (much easier than before the alignment, that's for sure). If I were to set my caster to 0.5°, then the corresponding camber angle (based on the '63 shop manual) is -2.0°... With modern radials on a typical car/light duty truck, don't you want the camber to be as close to 0° as possible to prevent inner and outer tread wear?

My mind is now a scrambled egg.

Les Schwab got the correct tires put on today. I asked the technician about the corrected caster angle and what not, to which he replied that he set the caster and camber according to the specifications that they have on file (2°-3°) and that he made those adjustments before putting the smaller, incorrect tires on. Therefore, it's tuned in for a level stance anyway. I drove it around a lot today and I am quite pleased with how it rides and handles.

Thanks to everyone who took the time to respond to my many questions. It means a lot.

Well, what do you think?
