Bell-housing alignment help

I am the simple one in this thread so I will state the simple questions. You never know.

1. when you set your dial indicator, are you setting it as close to perpendicular to the bellhousing ring as possible? See my pic below.

It is my experience that close enough isn't good enough with this. It needs to be as perpendicular as possible. I was out of spec and then came in spec when I figured out how to basically get my gauge in the hole and functioning.

2. When you zero out are you setting 0 to vertical? Follow up, when you reach 6 o'clock you are at .052 (+) or .048 (-)?

My issue was a combo on not torquing the bellhousing bolts down and not getting the gauge perpendicular.
