It takes some patience but the bakelite speaker plugs can be rewired without removing the rivets. Unsolder the wires from the plug. Strip about 1-1/2 inch of insulation off each wire. Then, tin just the tip of each wire, only about 1/8 of an inch. The wires are flexible enough that you can thread them through the back of the plug and into the pins. When the wires start to come through the pins, use a pair of pliers to pull the wires the rest of the way. It's not easy, but I have done this on several Philco speaker plugs.
