1. A picture of the gauge face that shows all of the face (no flash reflections). If you're getting up close to the gauge, make sure to set your digital camera to MACRO mode (usually indicated by an icon of a flower).

2. A part number. This is visible if you look up, under the trim ring at the top of the gauge. This number will be 914.641.10x.x0 No picture is necessary, just jot it down.

3. Date stamps off the back of the gauge. The components will be stamped with a month and year of production. Again, pictures aren't necessary here, just jot these down as well.
I know it's kind of a pain, but I'm hoping we can gather a lot of good information.
