Mike,
Here's the part numbers if that helps:
T2025500 Master Cylinder Assy (This is the complete assy)

These parts in this group would appear to be everything needed for a rebuild.
2020476-T0301 Connector set, M/CYL Rear
2020031-T0301 Piston Set
T2025512 Pushrod Assy
2020472-T0301 Circlip resov hose

A word to the wise is not necessary. It is the stupid ones who need the advice. Pat
