hi everyone can anyone please help with sourcing inner rear arch kits for my 2001 legacy saloon?

[rob 1965]

i am in the middle of restoring my 2001 legacy to her former glory. i have hit a snag as the car is in bits and i need these parts desperately i have tried automotive repair panels on facebook to no avail. They have the parts i need but never cant get them to answer the phone? The parts i need are inner arches and the car is a 2001 subaru legacy gx saloon. i would be so gratful if someone could help? Look foward to hearing something back  Kind Regards Robin
