I am looking for an original air box from a 2.2 Murena, complete with all it's brackets. My car has been converted to twin carbs, on pancake air filters, but I an planning to build a proper induction system, to do so I need the complete system as fitted to a standard down draft carburettor, to modify.
Can be found, once in a while at “Leboncoin” in France, kind of EBay.fr which you could try too
At Leboncoin search for Matra Murena in “equipement voitures”.
Kind regards from Belgium
