Im a lil confused on which plastic zetec inlet manifold to use on my 2ltr blacktop turbo.

The one that come with the engine is broke so cant use that.
My friend gave me another manifold which is the earlier 2 piece type but my throttle body wont fit,the bolt that holds the throttle cable on hits against one of the primarys.
Is this why on a frs they use the spacer plate between throttle body and manifold?

And why is it that some have more outlet pipes than others,iscv in different place etc
