NOTE: This is a custom part and may require modification to properly fit your build.  The front mounting holes are designed to fit Shovelhead motors, however due to the differences in frames, transmissions, and transmission location, it is possible that the rear hole does not properly center your transmission shaft and clutch bracket within the inner primary.  It may be necessary to slot the front holes in order to adjust the "Clocking" of the primary cover to properly center your clutch basket and avoid rubbing of your primary belt or chain on the edge of this inner primary.
