First of all,
I urge you to create an account on Peugeot Service Box :

In the bottom right corner, you can chose your language (English - South Africa). You will have to find a "cover", 'cause you can't register as "normal person", you must be a society (chose any little garage in your country).
That way, you will be able to look at a lot of drawings and, if you pay (the price is very low for 1 hour access), you could download all the tutorials you need !
The prices you give don't shock me : it's a normal price for this kind of shock, even in France
I read somewhere that reconditioning the controlled shocks is very difficult and expensive : it doesn't seem to be a good solution...
For the 407 Sedan 2.7 HDi, the part numbers for the rear shocks are :
- 5207 C8 (AMVAR) ;
- 5206 AY or 5206 FG (normal shocks) ;
- 5206 ER or 5206 FL (reinforced shocks).
For the 407 SW 2.7 HDi, the part numbers for the rear shocks are :
- 5207 C9 (AMVAR) ;
- 5206 AY or 5206 FA (normal shocks) ;
- 5206 ET or 5206 FH (reinforced shocks).
Unfortunately, none of these part numbers match with
the Coupé :
- 5207 C1, 5207 C3 or 5207 C7 (AMVAR) ;
- 5206 EX or 5206 FK (normal shocks).
I can not tell you what are the differences between the dampers of the different versions : the size ? the compression force ? the parts that compose them ? No idea...
For the top cups, the part number is
the same for all 3 vehicules (equiped with the 2.0 HDi 163 hp) : 5165 33.
Springs are different : 5102 K6 for the Sedan, 5102 K4 and 5102 K5 for the SW, 5102 CP (Standard) or 5102 N9 (Pack) for the Coupé
There's one thing I really don't understand : for the 2.7 V6 HDi, why Peugeot gives part numbers for "normal shocks" but nothing for the rings and top cups ???
As I already told you, all the V6 versions have been sold with the AMVAR, so why does Peugeot sells "normal shocks" without specific cups and springs ?!?! Weird !
