Re: more info for paint code
I concur, can't find a 510 code.
If you are trying to find out what color your car was originally, why not check underneath some of the items that are typically left in place on a typical repaint. Unless the car was completely and professionally restored, they more than likely did NOT remove:
Windshields, open up doors, beneath the cowl (piece behind hood and in front of windshield), behind dash, underneath most of the car interior, inside the storage compartments, gas tank flap, underneath the gas tank filler nozzle flange.
A complete and professional restore would have stripped all bolt on items off the car to repaint.
Once you've seen what the original color was, then go and compare that with the NAMES of the paints available for your year at zhome.com it just may be that it was a typo.
Hope it helps
