I cant help you with the hood emblems, but here are the pictures of the stuff I have that you asked about:
The spare tire carrier goes between the floor of the bed and the top piece goes under the lip at the top of the sidewall. You then tighten the center nut so that there is tension between the two and you don't drill anything. You then put the horizontal bar through one of the lug holes and tighten the wheel down with a lugnut. There is a hole in the end of the bar where you can put a padlock to lock it if you want. With the tire on the holder, you cannot access (or see) the actual tire holder so no one can loosen it and get it out of the bed. I ran my spare in my 72 this way and you can see it below in the picture of my signature (green truck).
Here are the 2 greed armrests
Here is the back where it is starting to come apart:
I have an extra black one that is actually in perfect condition which I don't need. It is for the same side of the truck that the one with the bad back is for, so I will throw it in and if you decide to paint them, you can use the two good ones and toss the one that is coming apart.
Here is the emergency flasher switch from my 69 for the glove box:
If you want them, send me a PM with your address and I will get them boxed up and get a quote for the shipping. I will use FedEx as it is closest to me (not cheapest though). So $50 for all of this plus whatever FexEx is going to charge.
