Pull the handle and bonnet and lift the ball assembly out. Two small rubber seats sitting on springs down in the valve body means this is your part. If the valve holds a single ceramic disc cartridge with nothing underneath it, it is a different design and this pack will not help.
The spout drips with the handle closed, water weeps past the ball when the faucet is off, or the faucet keeps running no matter how far the handle turns. Worn rubber seats and tired springs are the usual cause.
