the counterweight you need is the one that matches the rotors, a 91
the counterweights were made to use with the automatics from the factory, but have been utilized in the high performance market to adapt the aftermarket flywheels.
any aftermarket mazda rotary flywheel will bolt to the mazda auto counterweights

looks like roberts saying to leave the front counter weight alone and just swap the rear counter weight with one that matchs the rotors
