Welcome the Part Trace Casting Number Database Project. The goal of this project is to create the largest searchable database of engine and part number casting numbers on the internet. We currently have over 11,400 entries and are adding more all the time.
Here you will find information not only casting numbers and part numbers, but also engine and transmission identification codes, RPO option codes, vin, body, trim and paint codes. As well as information on how to decode them.
