No sorry dont have the part number, but i know the brand was Protex.
Yeh it was $55 for the master cylinder, i got a slave at the same time and the slave was $50. I couldnt believe how cheap it was. They (ABS at Springwood) give trade discounts to Sau members.
The guys there are really helpfull, one of the staff has a r32 so u could give them a call.
