Search for IKEA PAX Lyngdal Sekken guide rails

Hello, I need, due to the widening of my Pax, a guide rail each for the top and bottom for the sliding doors Lyngdal. The Sekken doors listed in the current catalog have the same rails. Maybe someone has some or knows where I can get them? Many thanks for the info. Best regards, Zant from Weiden

In the bargain cellar in Frankfurt, I saw rails.
