I am now in the process of restoring the upholstery in my Dearborn, Aug 12th, 1966 mustang fastback hipo GT. Need some help from those on the forum who have already done this process. I have bead blasted, primed and painted all of my frames. I have new TMI pony interior upholstery, American Cushion Industries seat foam, burlap, frame edge padding and the listing rods from NPD. The parts that I don't have new are the paper wrapped wires that connects the springs together. I would like to add new one to my bucket seats. But I have not found them listed for sale in any of the Mustang vendor catalogs. I found the paper wrapped wire on line, the stuff I found is 16-gauge wire while the stuff in my bucket seats is more like 12 gauge. The wire is tempered and has spring memory not like ordinary wire that bends and stays bent. Where can I find the correct paper wrapped 12-gauge wire. Thanks for the help.
