if its just the mounting screws that you want, i thinks i have a few spare sets as i usually change to s/steel. I guess they are a mix of about 4X M8 cap head bolts for footrests and the front mount under the seat. Then a couple of cap head M6 for the other mount under the seat near the rear light. Then a couple of cap head M6 bolts nuts and washers for the bar at the back that joins the two pannier rails.
could measure the length, but going to bed now.
