Ed, take on of the machine screws attaching the plastic sole plate to the router base down to the hardware store, they will fix you up. Purchase longer screws to fit through the table top into the router base. I exchanged the pan head machine screws with flat head screws and counter sunk the screw heads into the table top. If you are using plywood for the table top (recommended) I would suggest routing out some of the underside for your router table for the router base to sit in. The reduction of strength will be minimal and will give your router more vertical travel.
