Something to consider,... alignment machines set toe by degrees, not a fractional measurement like 1/16" or 1/8". I calculated degrees for my diameter of tire and 1/16" is about .14 degrees. In my post above, you'll see they got my toe set to .14 and .13. Close enough for me.
You likely won't get 3 degrees of positive caster without offset bushings. I have them in mine and as you can see they got about 4.9 degrees of positive caster. Probably more than I needed, but I DID ask them to get as much as they could, and it drives well.
