1970 SPORT FURY – SIDE HINGE COVERS FOR MANUAL BUCKET SEATS

Dear Friends

I'm looking for side plastic (black) hinge covers for manual bucket seats of my 1970 Sport Fury. I'm looking for OEM parts no repros... NOS or perfect used would be wonderful.
Is there anyone who can help me? I need pair L+R...
Thank you in advance!

Sebastian

P.S. Does anyone knows P/N of these parts?
