Hi all, I've been searching but every YouTube video or web page I can find for changing control arms on Mazda 6 seems to refer to the front suspension. Even the "rear lower control arm" hits are talking about the rear arms at the front corners of the car.

I want to swap the rear lower control arm at the back of the car (both sides) because they are rusting. I've located the correct part, which is GK2A 28 350D and around $115 USD shipped from the states. I just don't know how easy or hard it is to fit it? I'm attaching a pic, so if anyone knows how to replace this part please let me know?

Also rather than ship a pair from the states, I'd like to find a source in Europe, either UK or sweden, so can you point me towards a reliable online dealer? Thanks all. Pic of part attached. image.jpeg
