Here is a pair on Ebay, http://www.ebay.com/itm/1969-73-PLYMOUTH-FURY-FENDER-SKIRTS-/281315972903?pt=Vintage_Car_Truck_Parts_Accessories&hash=item417fbd1727&vxp=mtr
The 69 and 70 Fury's with fender skirts have U shaped lip (bottom of lip is flat) for the swing arm to latch the skirt. The handle will lay in this lip. You will also need a hole on the lower part of the lip for the pin you see sticking out.
