Do all stingrays have a black piece of plastic hanging from the rear cross member?
If so what is it's purpose?

Depends on whether its a convertible and/or a Z51. It also depends on which piece of plastic you are referring to, a picture would be worth a 1000 words.

If you are referring to the black air deflector under the rearend, it is for Z51 convertible to divert air to finned coolers on edif.
