Assuming you are needing to replace the exterior handle that always breaks. If you have a 93-96 model: Remove the small red and white lamp assembly at the lower rear corner of the interior door panel bby simply prying it out at the rear most edge with a flat screw driver. Unplug the lamp and set it aside. Remove the Phillips head screw exposed by removing the lamp. Next, remove the power window switch assembly by pulling up gently on the entire panel. Unplug the switch assembly and set that asside. There is a 5/16 bolt exposed that goes into the door body, remove that bolt. Next remove the plastic piece on the inside of the rear view mirror by carefully prying it off. Now, from the bottom of the door panel, lift the entire panel up and it will come away from the door body. Be careful as there are still a few plugs holding it in place. Reach in and unplug all the connections. Now place the door panel asside. NOTE; if working on a 97-98 model, the 5/16 bolt will not be found under the window switches, it is located behind a blank panel that is under the switches. You need not remove the switches, just pry down on the blank cover and the bolt will be exposed. The rest of the operation is the same as the 1993-1996 models.
Now you need to carefully remove the weather shield from the upper rear corner of the door body. 7/16 nuts (2) hold the door handle in place. And one 7/16 nut holds the door code button panel onto the door handle. Remove those nuts, find the rod that is connected to the door handle that moves downward when you lift the exterior handle. Unclip that rod from the door latch assembly. Next, find the rod that moves when you insert the key into the lock assembly on the door handle and unclip that rod from the door handle. follow the electrical plug from the inside of the key cylinder down to the the plug in connector about 2/3 of the way down the door. Unplug that connector. Now work the handle out of the opening, it is tricky but it does come out of there. Slide the U shaped clip off the lock cylinder and remove the cylinder.
Installation is the reverse of removal of course.
You have to remove the inside door panel to get access to the door handle nuts.
Try E-Bay, I see them from time to time and cheap
Your best bet is E-Bay, there's a few guys there that sell Mark Vlll parts only so that is where I'd look.
Inside the trunk on the inside fender, wire with a plastic handle. If you don't see it, it may have slipped behind the material.

Either the key pad on the drivers' door, the remote, or use the key.
I don't think so.
Disconnect the positive cable from battery, carefully remove the bolts attaching door panel and disconnect electrical connections and lower window before disconnecting battery and remove the two bolts holding the door handle on and remove the linkage and reverse for installing.
There is a sticker on the inside of the trunk on the trunk hinge.
