The door handles are NOT handed.
So you can swap them around form passenger to drivers door.
They have the actuator arms at both ends so if the drivers is broken and the passengers is fully ok, then you can swap them over and then both will work as new again.
You do not need to remove glass, at least not on a coupe model. I guess the volante should be same, however the glass needs to be up in order to reach some fittings.
With door closed from inside the glass should raise.
Once door card if removed, 2 or 3 screws on bottom, one behind door catch/lock lever and one within the finger pull tray.
Pull from bottom and door card comes away. If drivers then watch for mirror control wiring.
Once removed 3 large screws hold a panel across top of door on inside of glass. It's easier with this off.
Two 10mm nuts retain handle from inside with washers.
A bit fiddily and a wobble bar is best used to get the angle on a 3/8 socket.
The metal rod attaches using a plastic clip that has a plastic arm that clips over it to secure. Pop the clip back and remove the rod.
Handle should come out of door.
Awkward when first done but after that you should be able to get them in and out in record time.
I would say I could swap the two handles over in approx 30 minutes , start to finish and drive away.
First time would be 1 hr maybe longer if you take your time and also clean the lock mechs.
Definitely worth soaking the lock mech in WD-40 or other such lube cleaner, as the locks get sticky and thus cause the handle to break.
Also if your looking on Ebay for one,, check for MAZDA 323F Estate Handles ;-)
