Ha, I'm using that kit with a Brocken2 (that I previously used on my old Haswell CPU) in my secondary PC (with Ryzen 2700X) :)
Do you only need the screws or also that plate?
The version with the plate is not available anywhere (https://geizhals.eu/alpenfoehn-brocken-montagekit-fuer-amd-am4-84000000147-a1624293.html), just the screws are available at one seller for 6.14EUR (https://geizhals.de/alpenfoehn-am4-am5-upgrade-kit-brocken-serie-84000000215-a3107642.html).
Do you have Brocken2 or Brocken3?
