    Mammoth's are made to order model/serial numbers are useless unless you buying from OEM
    There is not better place for the working men than the union! 100% UA the only HVAC union!

    Dan,
    Just remove the entire motor and blade set and bring it to Dreisilker Electric.

    They will match it up for you.
