This kit contains everything needed to convert a MK5n Swerve Module Layout.
All parts of the MK5n Swerve Module are common between the "A" and "B" layouts, except for the Housing, Main Plate, and Shift Plate. This kit contains one of each of those three parts.
IMPORTANT Be sure to select the layout for your needs: Because the MK5n Swerve Module does not have a symmetric footprint, a mirrored layout is required. The two layouts are known as "A" and "B". The following illustrates the two swerve module layouts in a typical drivetrain:

The parts unique to Layout "A" will only work with a MK5n "A" Swerve Module, and the parts unique to Layout "B" will only work with a MK5n "B" Swerve Module.
