Before we even get to the decoding of the information in the lower boxes the first thing that stands out is the fonts used in both the upper text and filling out the information below that on your example does not match what I've typically seen and documented for San Jose during 1970 production. On your example it also lacks the coding in the upper right corner of that label
- Over stamp of the VIN is not common. VIN suggests a 70 Mach I with a 351 4V. Never seen a letter at the end of the VIN on one of these
- Body type "53" matches the code used to identify a Ford Custom 500 that year
- Color code "B" was not used in 70 for a Mustang application but was for other Ford models
- "3F" for the interior was not used for a Mustang that year
- "V" would normally be for a 3.91 traction lock rear end
- "X" would have been the code for a FMX transmission
- "71" was the coding for a car ordered from the Southern Calif district
Could be an older reproduction.
Here is another example from the same time period and plant to compare to
Also notice that on the one you posted the size of the label is much larger than the original example I posted
Hope this helps
