Dave,
I'll look at mine also. At a minimum I'll get the dimensions katy needs to calculate the angle.
In the article that 160B posted, it appears that the 20 degrees is not the full with of the slot. It looks like it is just the angle at the ball end of the arm when at the opposite sides of the slot.
