On Meyle HD FCABs you can change the bushings only as well.
But initially you have to purchase bushing career. Buy ones with the bushing pre-pressed.
Meyle HDs come with new nuts.
I believe there are two kinds. 60mm and 66mm, the later is the upgraded one.
Have you checked RMeuropean and fcpeuro? I am not where I got mine from, but was from one of them.
