The image marked "Where do these go" look to be parts to a standard wheel, so if it were me, into the "left-over parts" bin.
Otherwise, I heard it here before...these are like a Chinese Jigsaw Puzzles to figure out...add aftermarket junk to the mix and a perfect recipe for frustration. You might find a 10-year-old who can solve "Transformer" toys easily a handy helper on this one
As I said, one trouble might be that many if not most aftermarket parts to these wheels are terrible at best. Also, a slightly bent wheel will give you OTHER problems, yet the wheel might look great. The 67 wheel greatly differs in strength when set alongside a '65-'66 type, making them a bit weak and easily bent whilst cranking on the steering wheel of a PS car with the engine off (think of how hard the wheel would turn on a Big Block w/o the engine running) and/or in any (minor) collision.
The '65-'66 illustration you have is what I went by to reassemble mine but I did have to work at it a while to figure it out. I found myself reusing the original contact plates because the reproduction plates kept the horn switch "closed", meaning the horn would be ON all the time
(again, some of my parts are aftermarket or unconfirmed OE.) If you have an original wood wheel, you might just need to get OE or NOS parts. I wondered if it were not wiser to just by the reproduction wheel and get my frustrations OVER with, once and for all but I eventually got it together. After getting my wheel together and working on 2 of the 3 contacts, I bought some more OE parts (sold by Charles T.) from eBay. I am reluctant to try and tackle it again to change them out yet because I figured 2 out of 3 ain't bad
Going back a few years ago, I thought some of my problems might be my wheel is tweaked some...it too came from ebay many years ago and when I got it, I had to buy yet another pile of parts to get enough to make it right so back then I had over $500 (closer to $600) and it STILL wasn't right yet!
...only to see the reproduction wheels come available right afterwards. OK, I couldn't get the horn to work right but thought "at least the wheel looked like new" so I put it on the car, unplugged the horns since it was being stored anyways and stood back and marvelled how beautiful it was at least...THEN mice got into the car while it was being stored and the wheel became pitted some AAAHHHHH!!!!!!! lol! like I said...can be a bit frustrating but getting it "right" you will be pleased in the end.
