What's the best way to do this? I'm assuming both the top and bottom block areas are where to measure it being level (although I think I remember reading that only the top was level on the 9500ci's shifters??).
I tried doing it with a digital level after resetting it (calibrating it) for the garage being off-level (figured the car was off-level sitting in the garage). Got it to 0.5 degrees off. However, I'm wondering if I did it correctly since it's so hard to get a metal ruler to sit in the little square block in order to calibrate things.
