An assembly of a vehicle fixed bodywork panel and a support part for this fixed bodywork panel, comprising one adjustment means in translation of the fixed bodywork panel comprising: a translation member engaging said support part along a member translation axis; a through hole arranged into a first portion of the bodywork panel, the member translation axis being offset from the through-hole, and; a translation coupling element for the translation member and the fixed bodywork panel engaging the through hole, so that moving the translation member along the member translation axis causes a translation of the fixed bodywork panel relative to the support part in a translation direction allowing the fixed bodywork panel to be in a desired position, e.g. flush with a mobile bodywork panel.
