Where do I get alternator brushes


Hello All,

I suspect I need to change the brushes in my F78 alternator. Though i will do the checks with multimeter. Does anyone know where i can purchase new brushes from? Alternator info:
Make: Nippondenso
Daihatsu part no. 27030-87605
OEM no. 100210-3871

Look forward to receiving a reply, Nige.
