    0.56UH 0603 ±10% are normally used for the minus side circuit
    And,
    0.33UH 0805 ±10% are normally used for the plus side circuit

    I do not know how they are placed on the Rev: M board but suppose that the FB87/88 are on the plus side then you can use for both the 0.33UH
    And suppose that the 222/111 are on the minus side, you can use for both the 0.56UH

    However before you replace them, be sure that the 12v+ side circuit has no issues, normally these inductors does not interrupt if there is no short circuit or overloading.
    Also check the diode.
