my 406 2.0 HDI 90 diesel estate from 2000 started floating on the road last week. This week it got worse so I checked what is causing it and found this part broken:

I had no idea what it is called so I started my research.. I spent whole day yesterday trying to name the part and then order a replacement. This turned out to be a nightmare as this part that I identified as 'REAR SUSPENSION ARM' is absolutely nowhere to be found to buy. 0 linsting anywhere, 0 pictures of the part, nothing! And not only that, but there is also no video on youtube of anybody changing it.. the best I could find is a video of changing the bushes, but not the arm. there are videos for other cars but not a single 406... this is really strange as I usually have no problem to google up anything.. I have tried the usual as ebay, euro car parts, amazon, breakeryard various other car parts sites.. but when I search for 'rear suspension arm' or 'control arm' or similar it always gets me result for the front suspension arm which is like almost 90 degree bent boomerang shape.
I managed to find a replacement guide in haynes manual so that was encouraging that the part does exist

The guide mentioned that I will need a new inner bolt as well ad the old one will have to be cut off to prevent the whole suspension and subframe to be moved.
So then I found this thread from here with the exactly same problem:

the last post recommends a link where the part should be available: http://public.servicebox.peugeot.com/pages/index.jsp
So I went there I did my best to register and attempted to order, but I am not a garage or any kind of business and this website looks like it only serves these kind of customers.. I still managed to register somehow, put the parts I needed to my basket (all bolts+washers + the main rod only is £160 lol.. I think they should fly to my place and install it for that price) but I was not able to order/pay as I was not able to figure the website out.. it also doesnt help that it is in french heh. The error I get when I try to order is: 'Can not order: You are not attached to a PR Distributor'
I finally decided to register here and ask somebody for help as I pretty much hitting the wall here.. I am also a bit confused if there are left/right variants or it's universal for both sides as there is a little notch that holds a wire that when rotated it would be on the other side.. hmm. I could not find a left/right variant on the above website.
I need at least:
#1: 5175 E9 '02' REAR SUSPENSION ARM
#72: 6925 G9 NFP '02' (MUL) SCREW WITH EMBASE
and possibly the other bits:
#79, #12, #13, #70, #78
If anybody can point me to any direction how to order them from the website above or any other place that is willing to sell them to me that would be a great help.
