what is this piece called?????

[72freak]

Being new to the 60-66 era, I am a little unsure as to what a few of these pieces are called. I have decided to possibly put factory side trim back on this truck so I have started my trim search. Who sells it? Who has the best price on a complete set?

I have also been wondering what the piece that goes on the top, back of the cab is called so I can do a better search....I found a picture of it...Its pasted below.

Thanks
