To tighten the nut on the end of the shock, you don't need vice grips. Just a rattle gun is ok. Vice grips will munt up the shock anyway.

The big gland nut that holds the shock body in the strut has to be tight obviously. A hex style one can be tightened with a vice. The low profile style with 2 holes need circlip plyers, or better a fixed style spanner with 2 pins in it.

The brake disk shield should only be touching the strut and brake bracket of course. And should not touch the disk or another member which is moving in a different plane. Thankfully, you don't need the brake shield, and I don't use one. (Ford Falcons don't have them, but this means nothing to me).

You can calculate your own camber change with grade 6 maths. Trigonometry at it's most basic. If you know the effective length of the strut, and the difference in control arm length, surely you can find the approx change in angle?
