Yes ,its a complete new part.
First i had the low breather cover and put the batterie on it. > enough space
Then i made a breather cover that serves at the same time as batterie holder.
Has the size of batterie and is fixed with the scews of breather cover with the srews sunked to have an smooth surface.
It has a narrow rand of about 2/3 inch hight to hold the batterie in place ,and the breather tube is placed in front of it . This way the tube goes straigt upwards to airbox.
Sorry, cant take no pics at the moment
