i don't know whether it's the same for facelifts, but on my '96 and '99 meegas i had to change a handle/lock.
yes the whole box had to come out but it wasn't too tricky and thankfully haynes had some advice.
in summary (not summery, as the weather is right now 8-)) from memory....
there's a few screws (4 i think) holding the bottom of the box in from the front.
there might've been some screws from the side as well....prize the side cover (open door - with the airbag sticker) off and use a long screwdriver to get to these. not all mind, as they're for holding airvents in as much as the box.
there's also three bolts (hex key) going from the top of the glovebox to the airbag and a couple of screws holding the passenger airbag over the top, you kind of undo the lot and lift the airbag up a bit.
you have to disconnect the plugs from the light as it slides forward. oh and maybe the aircon pipe too.
once out, the lid has loads of little screws holding it's velvety liner on. once that's off you can get to the handle ok! but if you're taking the barrel out (i'd suggest really don't!) watch out for loads of little springs! basically it'll be lockable with any key after as there's no way you'll get all the lock gubbins in ok i think.
at the time i also changed some dash bulbs and re-set some airvents that had had a bash!
hope that's of some use....
