I would have to do a little more research, but its not out of the possibility, the stamping maybe "9R120470"
If in the attached photo is 120470 then everything matches on the car.
I'd definitely agree with "9R120470". You can easily see...
Maybe 3,5,6,8,9 or 0
/ something
/ then the bottom of a 1 or 7
/ definitely bottom of a 2
/ maybe 3,5,6,8,9 or 0
/ definitely bottom of a 4
/ bottom of a 1 or 7
/ maybe 3,5,6,8,9 or 0.
The obvious known digits line up perfectly with 9R120470, and the "not sure" digits are pretty easy to match up once you know the VIN digits to compare with.
Very cool! Seems like the OP has a great example to match his date codes to as well!
