850i 1991 front & rear suspensions

I need to change my front & rear suspensions.

I am based in Hong Kong & no workshop including BMW can get the parts in the net 3 months !!!

1/ Would you know if I could adapt suspensions of more recent BMW models ? some M3 series for example....

2/ Would you know where & for how much I could get these parts from Germany or France ? I would not mind get them there & ship them back by FedEx.

Thanks a lot for your help.

I meant the rubber

Thanks
