Vin location and decode help!

Hey Guys and Gals

Trying to decode the vin and fender tag on my 1964 Plymouth Sport Fury and keep running into some snags.

First snag I can't find the VIN tag.

The registration says the VIN is 3441xxxxxx (last 6 sequance numbers x'd out for safety)

From this I get:
(3) Plymouth V8
(4) Premium price point
(4) 1964 Model Year
(1) Detroit Lynch Road plant

Easy to decode, just can't find it to confirm.

I can however find the options tag on the Fender, but can't decode it.

it reads:

30 103
063 15 838 12 8
0316 0473 342 P4X PP

From this all I can decode is:
(063) 8.55x14 WSW Tires
(342) Torqueflite 1962-63 & 66

Nothing else comes up!

Can anyone shed some light on this please?
