I have had success setting the toe with the TrackAce laser. A link is below and it looks like it is $140 shipped. I have used it many times and it is quite accurate. Once the toe is set then centering the steering wheel is fairly easy.
For the camber I use a wheel level to make the sides symmetrical. The rear should be zero or slightly positive. A negative rear camber will wear the inside of wide tires on a Pantera. Each time the rear suspension on a Pantera compresses the camber goes more negative.
