I have modified an ASPL A3007 listed for Espace Series I petrol to fit the Murena by removing the pulley wheel, front mounting flange, and bearing. Then fitting the bearing in an original Murena alternator front mounting flange. Finally putting the original flange on the new alternator stator and rotor axle - it fits perfectly.
The long screws holding the alternator together can be removed by carefully removing the back plastic cover (removing any nuts and tabs in the way), removing the nuts and gently tapping them to release them from the flange. You will need a puller to get the front flanges off the old and new alternators. The front nut on the pulley wheel is most easily removed and refitted using a strong electric or pneumatic impact wrench. The bearing can be removed from the flange using a size 22 mm socket.
There's a rear mounting flange fitted in the Series I Espace alternator is not needed on the Murena.
The part I used is this:
