Could some please tell me how to find the missing part… derailleur arm on the back missing its a GRX derailleur having trouble finding the exact part with the screws to fix
Your rear derailleur is the Shimano GRX RD-RX812. It would’ve been helpful to the community if you looked under your derailleur and told us. Would have saved 50% of the effort.

Shimano’s part numbering system is wild, half the time the GRX parts are listed under XT or Ultegra listings with no indication they fit GRX.
