Camber adjustment

[alga]

I opted to go for the book design of camber adjusters, I figured I wouldn't be tuning the geometry all the time. However when I got the wishbones assembled, it turned out that once the balljoint nut got tightened just a bit getting the balljoint out of the mushroom for adjustment in place is nearly impossible. It's easier to price the mushroom out of the upright, although that's not really easy either. So, how do you do it?
