Does anyone know how to decode the various number and letter codes on different body parts. For example, under my sill plates, on the rocker panels, the code "089M511" is stamped on both sides. I spoke with a very knowledgable Mopar guy, who told me it indicates a date of November 1969. He did not tell me how he got the information, but he was right, my 70 Challenger was built Nov 11th 1969. I have seen codes like this on deck lids, hoods, fenders, etc. Is this info in one of Galens books? Who has it?
