My 850 just got an advisory on the rear chassis legs and towbar corrosion, so I thought I'd make a job of it whilst I'm waiting for my wheels to be refurbished.
I've got some trailing arm bushes and tool, but when I replaced the rear shocks/springs, I noticed the top washer was like a pie crust. E.g.

Are they easily available (part number 1387906)? Not listed on PFS or ebay but seem to be available abroad - with quite high shipping costs.
Secondly, I sense some welding is needed. Where might the ECU be located in case I need to remove it?
Thirdly, I wondered whether the ride quality might be enhanced by replacing the rear springs. I fitted the Novomat conversion kits from PFS about 5 years ago, and it seems a little bouncy and crashy. It is much better when the tank is full of diesel, or when there are people in the car. They do an Eibach kit for £180 all round which people seem to rate. As the front shock mount seems a little clunky, I could do that at the same time.
All advice/thoughts welcome!
