lower arm replacement help

[springs]

hi i have a phase 3 2000 306 xsi that needs a new n/s lower arm im having trouble finding one .
i have only managed to find a phase 1 and a phase 3 arm the site said it will fit 10/1998 TO 06/2002 ALL MODELS
will this fit my car cheers

as per the ones above that say it fits from 1998 to 2002 models.. yours is a 2000 model which fits in that range.

The main thing you need to confirm is if the balljoints are 16mm or 18mm. The phase 3's should have 18mm balljoints on the wishbones
