I'm recovering the seats in my 64 falcon. I purchased new seat covers and started stripping the old seat. The wire that threads through the fabric loop for the seat bottom and top center pads is missing. This is the wire that the hog rings grab, securing the seat center pads to the frame. Memory tells me that I need this special HARD wire and cannot use off the shelf wire as it will bend too much. I'm considering using some 1/8th inch round bar but wanted ot see if anyone had a source for the correct material. thanks -shane
