Basket Case Parts ID

[sick472]

Help me ID these parts please. I would love to tell you folks that I bought a basket case project, but I actually created it myself. I started taking the truck apart in 1997 and have moved 5 times since then along with a fair amount of life in between. So I have forgotten where the photo'd parts go. Here are the only hints I have...

Part #1 - I think they go to the door, but why do I have an odd number and different sizes. I had 72 super interior.

Parts #2 and 3 look like hole plugs or the whitish ones look like light lens'.

4,5,6 & 7 go under the dash some where, I think. A photo of them installed would be great.

#8 - Pretty sure this is for the front behind the 72 grill and below the hood latch, but what does it attach to on the bottom right as pictured. This connection would be near the bumper facing forward.

#9 - Not sure, but it looks like it was broken at some point near the two hole on the left as pictured and may not all be there.

#10 - Under the dash maybe?

#11 - I have three of these along the top of the gas tank already installed in the cab, but I don't know why I have 3 more.

12, 13, 14 & 15 - ????

#16 - Chrome spring loaded hole plugs, but where do they go.

#17 - Under the dash somewhere?

Can anyone feel my pain? All help is appreciated!
