Simon because the Addco bars only have the one hole like the stock bar my fabricator made the mounting point on the control arm adjustable. There are two flat plates welded on top of the control with 5 holes; the middle hole lines up with the stock mounting point, the ones either side are in board or out board of that, moving the mount changes the leverage the control arm exerts on the sway bar. When I had him lengthen the control arms and when it was done added the the brackets for adjustability.
