Qashqai +2 J10 1.6 117 PS rear crossbars

Moin municipality, I’m normally in the VAG area. Now I have to replace the crossbars with the Qashqai +2 J10 1.6 117 HP crossbars (pulls) at the rear. Getting the crossbars and excenter screws with nuts and disc is no problem. I also want to have the attachment on the wheel side and the attachment on the crossbar in the middle when I’m at the screw. The center (excenter screw, fixing kit) is OE 55226-EN10B. I get it everywhere. st 54459EN10A or 54459JV00D (which of the two bolts is it) and nut 01223N2011. Which bolts, discs, nuts do I need on the wheel side. And where do I get all the stuff except at Nissan? Here in Germany these few screws cost over 50€ without the excenter set. Original Nissan screws and nuts cost e.g. at Nissan in the USA cents. Thank you for the information!
