Part Name, Parts needed

Can someone help me out with a part name. Ive searched Hi and Low to find the name of the lens/ light Above the brake lights and below the hatchback, But with no luck. What is that strip called. Also, if someone has one for sale, I could use one.
I recently purchased a 90 NA Z, and need alot of OEM items :(, im learning as I go to some of the mistakes when purchasing a used z. However I'm slowly but surely fixing it up to where I want it to be.

I'd go to a junk yard for OEM stuff like that.

I'm guessing you mean this:

And I would try to find a good one in a junk yard as well, as new OEM Nissan parts are quite pricey.

this company carries those third brake light for the z at a very reasonable price. plus it will be brand new so it wont be all maroonish like most used ones are because the sun that fades the black.
