in dire need of some 68 Barracuda parts

Hello everyone, I am a rookie to this sight. I have a non-original Triple Black 1968 Barracuda Convertible that is in need of some apparently elusive parts. The car is a driver, not a show quality car, therefore nice used pieces would be great. If not available, then it will be new pieces if I can find/afford them.

1. There are two (aluminum?) trim pieces that go across the width of the trunk lid between the tail lights. I am in need of the lower piece, but would be interested in both pieces if they are in decent shape, or insight as to where I can purchase new piece(s).
2. chrome/stainless trim that goes across the bottom of the windshield.
3. any of the clear plastic gauge covers and dash knobs.
4. complete ashtray assembly that is in the dash.
5. ashtrays (2) that are in back seat side panels. Can buy new ones $125! WOW!
6. Black rear armrests. They are an irregular shape, not rectangular as most that I have found. At what would be the rear of each piece, it comes almost to a point to one side, congruent with the shaping of the side panels pre-formed ledge that the armrest sits on. Hard to describe. There aren't any bolts or holes through which they are attached, rather there are two clips on the bottom and the armrests are pushed onto the top of the side panels' ledge. confused yet? I haven't found these ANYWHERE.
7. console top pieces and automatic shifter knob, again they are available new $$. Mine are BADLY pitted.
8. Top and bottom(2 piece) dash pads. My top is very badly cracked/worn, two bottom pieces are just rock hard. Prefer dash pads over the covers that you can glue on top of the originals, just due to the poor state of mine.
9. White plastic windshield washer fluid container (that's a mouthful), foot pump type, not electric. $60 new. Might just hook up a container of fluid that you buy at the gas station! lol

I have been pounding the proverbial internet highway(pavement) in search of the above parts, but have realized that right here is quite a more knowledgable group of enthusiasts than I am. Any and all advice/assistance will be greatly appreciated.

Thank-you and sorry for being so needy on my first post,
David, another crazy canuck
