Where does the book say Gajanan Maharaj met Mhalasapati?

The provided text does not state that Gajanan Maharaj met Mhalasapati. According to the information in Chapter 0, it was a different holy man, referred to as "Maharaj," who entered the Khandoba temple and met Mhalasapati. It was during this encounter that Mhalasapati greeted him by saying "Aavo Sai Baba," and this individual became known as Sai Baba. The passages describe Mhalasapati's background as a goldsmith and devotee of Khandoba, but his interactions are explicitly with the person who became Sai Baba, not Gajanan Maharaj, who is absent from this account.
