Track rod end sleeve that belongs to the hub help

Had a phone call from the garage as mine is in having the track rod ends done as there was a huge amount of play in it , now the previous person has replaced the track rod ends before I bought the car and the sleeve that belongs to the hub, Ino welds itself onto the old track rod end and you don't want to throw this away :...... well the previous owner has thrown away the sleeve on one side and it's missing , Iv been looking online and can't find one anywhere , spoke to Renault and there saying you have to buy a whole new hub Anyone no where I could get a replacement sleeve ????
