Can someone tell me if this information makes sense:
Silver 1970 911s : made 3/70 (stamped on driver door)
vin 9110301274
Engine number 6301713
The VIN and the Engine numbers match but
according to some of the sources I have read it would mean that this car was made in 1969 but might be sold as a 1970 model. But the info on the drivers door clearly states 3/70 as date of manufactory.

Also what are the significance of these numbers stamped on various parts of the engine:
cooling fan housing : 9011061015R
middle airstack on Right: 911 110303R
rear of Right cylinder bank: 911402

Thanks for any enlightenment.
