Ok Steve, least you know.

Caster can be roughly checked with a plumb bob and protractor. hang the plumb bob so it intersects the center of the lower ball joint. Use a projector ( I have a marine version) to measure the caster angle. ( ie a line thru the bottom and top ball joints from the perpendicular). You can buy a tool but it will get little use.

Shims either side of the top ball joint total three. The width of the top ball joint body, plus 3 shims plus the offset of the arms equal the length of the inner pivot shaft. more shims and you'll be inducing stress to the top arms.

Rear toe.....a debatable subject and a bit involved for this short space. My rear will be set with 1/8" of toe.

It's a topical discussion because the jag is so difficult to change rear toe as it's done with shims under the control arm inner brackets. If it was an easy adjustment folks would try it and test the results.

Cheers
