Hello Holly,
I can understand you being the parts chaser, otherwise you are paying the mechanic for his time to do so.
Having said that, I don’t know exactly how you are going about this, where you have looked to date, whether you are set on secondhand parts, and all important - do you know the part number of the hub you are searching for.
Perhaps you could colour in this detail for us Holly.
Regards,
Gareth.
