You can do a quick survey with your no-go gage. Place a piece of blue painters tape on the bolt end of the no-go gage. Trim the tape so it doesn't wrap over any edge. it should be a flat little circle.

Then try again with the gage. The tape is a poor mans way of lengthening the gage a little. Add tape until the bolt doesn't close and then measure the thickness of the tape.

Add the tape thickness to the no-go dimension and see if it's less then the field measurement.

This isn't terrible accurate but it should get you in the ball park until you can pick up a field gage.
