'63 Valiant Newbie

Greetings,

I finally found the Gen II wagon I've been looking for. I took delivery today!

Along with it, I received boxes of parts - some of which I don't recognize. Can someone tell me what these are (were) for?

Also - if a 170 cid /6 was still an option in 1963, how do I tell if I have that, or a 225? And cast block or aluminum? Can you tell from the data plate?

And, where was this data plate affixed? (The VIN plate is still on the driver's A pillar.) Is there a key to decoding?

Thanks in advance for all the Newbie questions! Excited to finally own an A Body.
