Xperia Z3 vibration unit

Sup XDA,

Have been looking everywhere on the interwebz for a vibration unit - or something similar - like that for the Xperia Z3 (D6603).
It can't be found, so how do I repair my defective vibration unit? For the Xperia Z, Xperia Z1, Xperia Z Tablet and such it's just buyable everywhere! (e.g. eBay)

Thanks in advanced for someone whom helps me fix my phone.
