There were no stamps under the heater box on my car. .that was the first place I checked because I had read there might be a partial VIN under there but no luck. I have no reason to suspect anything fishy regarding the authenticity of my car though....I have owned it for 30 years and know some of it's previous history so I am fairly confident with what I have. I just figured since I had it down to it's bare nothings...it would be a good time to document stuff for later.
And I am naturally curious and am interested in is this sort of stuff.
As best as I can tell....there appears to be two basic stamp conventions....one for the individual stamped panels that were welded together to make up the Fisher Body portion of the car and another type used on the panels bolted on the car at the final assembly plant. The Fisher Body panels were stamped with a letter followed by a 2 digit number (sometimes 2 letters and two numbers). I think the letter(s) corresponds to a stamp or die department and the 2 digit number is the week of the year. Panels that have left and right versions also carry a separate 5 digit number that appears to be a part number since they different by one digit at the end.
Almost every panel on my car body was stamped in the 17th, 18th or 19th week. My car was assembled during the 21st week so the dates work out well.
The off body parts...fenders, hood, core support etc have a different code it seems. The code on the fender is 5A15M. Not sure how to decode....the 5 could be month of May...the A could be the assembly plant (my car was assembled in Arlington)...the 14 could be day of the month and perhaps the M could be a die code? Just guessing though....not really sure what it all means.
Here are some photos of the body panel stamps that I found.
