I make those axle flange gaskets from very soft aluminum sheet metal about .030" thick, using the dimensions of the hub and the bolt hole diameter and spacing as a pattern. They seem to work better and last longer than gasket paper, especially if the flange doesn't have tapered collets that keep the axle from shifting slightly forward and back on the studs.
