your diagram is inaccurate, lets concentrate on #10, and those fasteners, the rest of the diagram i dont know; #10 for me is much different, and to speak ive been to the vw dealer about this 'type' of pic, cause i dont know what model or how that(yours) looks -(#9), and the (#10) fasteners can work and adjust. (the bolt going thru my #9 is the adjustment) although my #9 is part of #10 but to the right,, etc, etc. but to say my vw (dealers)pic is inaccurate and not helpful. i dont have anything your going to find at which store.? unless you think of washers, and nilok nuts.
can also try napa and look at their pic. (just guessing at accuracy of pic)
