Caster angle question

[drummerdad]

I dont see how it would be adjustable with these parts. The upper a-arms have camber adjustments. But I dont see any caster adjustments, unless it can be done with the ball joints. I had not thought about the caster changing when I adjust the rear ride height. It needs to go up maybe 1" to 1-1/2", maybe 2" but no more than that. That will change it, maybe 1/2 degree to the negative. Again, this is all just preliminary, but it should be close.
