Auto part seeking auto for happy relationship

I find myself in possession of a mystery GM seat belt extender. The only thing I know about it is that it does *not* work with the 2003 Chevy Malibu. There is a code stamped on the buckle that might be a part number, but typing that into any of the GM auto parts web sites I was able to find did not produce any results.

Any ideas how to find out which car it belongs to? It's not important, but if I can find out I can give it away instead of cluttering up the landfill with it. ETA: Auto part has found a new home!
