    Default VIN / RPO Code Deciphering

    I just purchased my listed vehicle and am looking to find out what options / rear end gear ratios were installed factory. I did a search and didn't find anything, so does anyone know where I can find a list that deciphers the VIN and RPO codes? Thanks in advance.

    This site decodes VIN numbers:

    What I am wondering, is there a site that decodes the features within the VIN number?
