Quick question about ARB bushes

[Old Boy]

How many are there on the ARB?

Don't have the car to hand but need to order some new bushes from here asap.

I'm guessing at 2.

Are they all the same? Link I posted doesn't have picures of the bushes.
Just read another thread which said the ARB links are usually to blame for grinding noise when cornering rather than the bushes.
My mechanic is saying to change the whole ARB, which looks expensive.

They are different sizes, think there is 2 different options. Depends on the diamater of the ARB IIRC
