This is the flange only from the first photo that fits the clutch housing shown in the second photo (HOUSING IS NOT INCLUDED JUST THE FLANGE FROM THE 1st PHOTO). If you have this style cover (2nd PHOTO) then the flange is required for the secondary.
This is required for the STM secondary clutch installation on the 2014-15 Maverick with the new updated clutch cover. This is an adaptor for the stock clutch housing cover to remove the bolt in funnel over the secondary for clearance to fit the STM Secondary clutch.
