Topic: intake manifold

[gasr55]

I am trying to identify the type of intake manifold that i have on my 1988 5.0 mustang gt! The manifold has no manufacturers markings on it but it is marked with 8011 in big bold numbers on the rear.
  I have googled that number and have found only references to wieand intake manifolds but i am not sure if i can assume that this is what i have!
 Does anybody have any ideas or comments?
