605 Shocker Fluid and Pressures

[reesie_baby]

Hi,
My Dad mentioned that he required what fluid goes into the shocker to engine mounting on his Peugeot 605 SVDT 2.5 He said that it has a shrader valve on top of it and that he needs to know what it is and what pressure to do it to. Also would anyone know where he could go to get it done if the job is unable to be done by himself as all Peugeot Garages he has rang have never worked on a 605 but one did and they said it was a 2hr job for each shocker. Please could someone help me with this.
He also asked me if anyone would tell me what the rear suspension top pressures were and that he thinks they are hydro elastic mountings.
Hope that you can help.
