GM parts wiki

I think I have finally found a source for official GM part numbers. If you have the correct GM OEM part number it makes your search for a part much easier, especially when using google, ebay, amazon, etc. You fill in your part name in the box at the bottom of the screen, then fill in the particulars of your vehicle on the next page. I found the OEM GM part number for my one year only 83 turn signal lever with cruise control switch quickly. It looks like an online collection of various GM parts catalogs.
