I got hold of some perspex and made the turn plates today. I was pretty happy when the caster measurement came up very close to the readings from the suspension place - see passenger side below.
Then I fitted the longer bolt to the front of the cross pin on the passenger side (see below) and managed to get about 4 degrees of caster but couldn't go any further as the shorter bolt was starting to bend.
I don't like the idea of tightening everything up at such an angle so I'm going to buy some
adjustable top A-arms from summit and do away with the shims. Requires a new strut to accommodate a different top ball joint but it makes the whole thing a lot easier to adjust.
If you're wondering why on earth I'm going to so much trouble to achieve some fairly standard suspension settings - SO AM I!!
