Type your number plate into your parts website of choice (I normally use AUTODOC) and it will give you the right parts. You can then chose what brand to go with, I used Febi for my 1.4i, though febi part quality can be very hit or miss. The bearings looked on the higher quality side of the Febi stuff I’ve seen though, and for £36 each I’m not going to be too annoyed if I need to change them again in a couple of years.
The other thing is replacing the bearings is a bit of a pain, not a super easy job if you are doing it yourself. You’ll need a compatible VAG style bearing puller, and it is well worth following the service manual, as the bearing will be damaged if pressed in incorrectly.
Hopefully some useful information there from my experience with it all,
