Donor for 63 dart GT

So I was hoping that somebody could help me with decoding the fender tag. Pretty sure it’s a 225 wondering if the three speed was full synchro or not and with the rear end being from an automatic how much difference does that make as far as gearing, compared to my 63. Again, thank you to anybody who takes their time to answer my question.

Post up a good picture of the fender tag and will also need the 4 digit of the VIN so I know what assembly plant it was built at.
