I am assembling a set of adjustable control arms from parts. I now there is a 10 degree "cant" between the upper arm and the ball joint plate. I don't want to assemble this upside down. So, the easiest way to pose the question and avoid confusion:
.
If the upper arm is installed and perfectly horizontal, does the ball joint plate at the end tilt "up" 10 degrees or does the ball joint plate tilt "down" 10 degrees?
