I've browsed through the different links, videos and information you guys have posted about removing the interior door panels on the 129, but no diagrams or instructions seem to apply to my 1999. It looks different, for example I have the lock on top of the panel and not next to the handle, and it appears that I have airbags in both doors.

Victor,
The zip file is the instructions for a '99. Remember to disconnect the neg side of battery, and since I believe in 'belts & suspenders' when fooling with safety equipment/systems, disconnect the airbag; red plug(s) in the passenger footwell, too.
