    I use a set of wire spark plug gauges that I got from Ace Hardware or a local Auto Parts store. These are usually in thousands but you can go on line or with an app make the conversion to millimeters. The wire gauges won’t be exactly hundredths of a millimeter but you can get an good approximation. When I try to measure the girdle with my feeler gauges, my hands are not steady enough to be exact, but I can get real close.
