Your overhaul will be easier to execute and with a more professional outcome when you specify new OE parts like this PlugPin rather than making do with the old corroded, maybe slightly damaged item.
For other new parts to make your task easier and with better results check out our online schematic for your model.
Any machine is only as good as the quality and precision of its fasteners.
Use OE fasteners - why take the chance with any other make.
