How to Find GM Parts Numbers
If you own a GM car, you may need to order parts at some time during the life of your vehicle. To order the correct part, you will need the official part number. GM parts usually have a number on them, but this is not the official part number. It is a casing number. Attempting to order the part you need with the casing number will not work.
