Can’t easily cant the upper.

We will see what’s what when I swap the arms in . Wait, maybe I can get a measurement from the burned out van I bought. Believe it or not the rear springs have collapsed from the heat of the fire. So it’s sitting at, in essence, full compression. I’ll see if I can get a pic showing relative angles at that position
