Clint Eastwood's soon-to-be ex-wife is looking to make some pocket change ... she's going back to her roots -- figuratively -- TMZ has learned Dina Eastwood is going back to anchoring the news at her old TV station.

People at KSBW in Monterey, CA tell TMZ ... Dina will be anchoring the 5PM newscast beginning today and will appear part-time on the newscasts.  The News Director, Lawton Dodd, tells TMZ, Dina will be anchoring daily for the next 2 weeks (SWEEPS!) and will come back from time to time.

Dina was an anchor between 1991 and 1996.  She met Clint in 1992, when she interviewed him for the newscast.

Dina filed for divorce last month.   There are reports Clint had an iron-clad prenup so ... every little bit helps.
