Backinblack is correct, I haven't done a 'rose' joint on an L322 but I've done similar on some mercs, the reason it's called a rose is because it's a bush within a bush, for extra articulation to compensate for anti-dive/squat and a modicum of active toe.
Alas easier to fit than remove, BIB's kit are the tools you need, but can be done with with off-cuts of tubular steel, threaded rod and the longer (25mm) nuts.
'Rose bushes' I believe are a brand of 'all-metal' spherical rod end/bearings like wot you put on race/rally cars, they are much strongerer than a standard item.
