Hi, this looks like forum I had looked for. I was impressed to find zip files of shop manuals and signed in for 1st time ever on any forum. Some weeks ago I managed to get 64 sedan Impala 4 door and project is starting. I have some trouble finding / understanding codes of original assembly. VIN number I can now decode. Does TRIM number 866 on plate mean for sure what are original interior colors ? I would not like to order floor carpet in wrong color from US to Finland... Antti
