Jim! You've done this before--huh? Without removing the ebrake assembly, it might be next to impossible. Maybe not, but there is a good chance you'll break it.
Without the ebrake as an obstical, the kick panel is an easy out and in, if rolling around down in the area to remove the screws is classified as an easy repair.
With the ebrake and sill plate out of the way: Take 2 butterknives, and bend a 90' about 1" to 1.5" back from the tip. (The wider the butterknife, the better.) At the top, insert the first butterknife between the kickpanel and the are where it covers the dogleg. Slide it down and pull out gently.
While holding gentel pressure with the first butterknife, insert the second butterknife in from the top and gently pry the kickpanel off of the dogleg. Keep working down, using the first knife as the first part of the pry and the second kife as the final part of the pry.
After you get the lip pried off, you will have to gentely pry the kickpanel from the bed of dum-dum that seals it to the body. It might take a little more than gentle, but don't get too agressive.
When you reinstall it, you want to freshen up the sealed area with more dum-dum (amatures call it strip caulk). And cover the screw holes. Install the cover in the hole and reverse the process with the butteknives--hooking the kickpanel lip over the dogleg, but you can probabally do it with one knife rather than the 2 to remove it.
Once you get it in place, use a small probe that will go through the holes in the metal. With the probe, fish around through the hole in the kickpanel until you locate the hole in the body, then start the screw. Just start the screw, and continue to fish out the rest of the holes before tigtening them.
Watertest with a big blast of water--a hose on full blast without a nozzel on it--after you finish. It should be able to take whatever water you can dump in there with a hose without leaking. If it leaks under this extreeme setting, you can rest assured it will leak in normal rain. Well, you can rest assured that it will leak if you are charging someone for the repair.
