I'm running 3 deg +castor and 3 deg -camber on the track car. As I have only driven it on and off the car trailer I have no idea how it will drive. This was just the initial setup recommended to me.
I have been using a digital spirit level and protractor for a while now and it makes life so easy. You should be able to get that angle between your red and blue line to the nearest degree I would think?
 
As I mentioned before, I had to get the longer control arm ends, I think the steering rod ends will make it ok 
 

Trying to remember what my mk2 was at, it's got all factory parts except the Selby swaybar that's 24mm thick. Factory as in Ford parts bin, Capri struts and springs, mk2 cortina roller tops but a sneakily fitted Hillman Hunter spring tops , they are up side down version of escort ones which allow to lower without cut springs.!

Taking it to a align shop Way back when, the guy said I've about 3 to 3.5 neg camber and the struts also about 3 on caster, he said at full lock it's at 8 deg!! BMW style Ackerman..

Crush tubes should do the trick, just add a smidge of grease on the swaybar so the tube doesn't seize up, I've cut so many off because of it..
