It appears the black 120 would need modifying as there are slots right & left on the center bar, but no center hole.
A couple of coats of black from a rattle can would convert the red 120.
EDIT: I am not sure if the red 120 is properly depicted in the description.
It appears the Z3 model is the 140mm bracket with a center hole, and the Z2 is the 120mm bracket with no center hole.
PPCs website is full of errors, and generally I confirm what is shown prior to purchase.
