Been so busy too with work, weather & home did not even order it yet should be the same color as your but does the metal bracket come with it mine may be broke? So i may just order it in case I need it! You say you can do all this with out removing the seat don't seem to be all that much room!???
No, the metal bracket did not come with the switch panel and I do not think yours is damaged but it's easy to check it out. Just take a flash light and gently pull the top of the switch panel toward you, away from the side of the seat and you'll see it. There are only 2 mounting points at the top of the panel and if yours is sagging down in the back, that means that both of the upper mounts are broken as well as the 2 bottom side mounts leaving the 1 bottom mount holding the whole assembly in 'Place?'
About the room for the screw driver, there is about 2 to 3 inches of room to get a #2 Philips head screw-driver under the side to remove and replace the mounting screws. The rear side screw is the tightest one to work with and I pretty sure I'll have to use my 1/4 inch rachet set with a #2 Philips head bit to replace this one. 4 out of the 5 mounting points were broken leaving the front underneath screw to remove and the whole panel just dropped down which made it a lot easier to remove the side screws. After studying the passenger side, it is qiute apparent that there will not be enough room for my fat hands to be able to work the regular screw-driver from the side but with raising the back of the seat up as far as it will go and lowering the front down as far as it will go and also moving the seat all the way forward there's enough room to get the small rachet system in and work from the back. Of course for the other 2 screws you just need to raise the set all the way up for those.
This is the kinda job my deased wife, with her small hands had no problem doing as long as I was there to tell her which way to turn the screw.

(Righty Tighty, Lefty Lousey gets confusing screwing from the bottom up.

That always reminds me of when I was teaching a class for Machinist and a student was Tapping (threading a hole) in a piece of angle iron with the side adjacent up, interfering with the Tap Handle and only allowing the student to turn the Tap 180 Degrees at a time. When I ask him why he didn't turn the part over and Tap it from the other side, his reply was, "Because I have to have a RIGHT-HAND THREAD, NOT A LEFT-HAND THREAD!"
At this point, I realized I had to stop the class and take a step back and go over the difference between the Right and Left-Hand threads from the different directions i.e. up, down, back and forth. Surprisingly, not all my students could understand my 2D drawings on the chaulk board and what I ended up doing was to empty my coffee out of my thermos and showing the class the difference of the direction of the thread depends on the viewing position.
That example could not be disputed by any of my students.
That was a real lesson learned for me on how to improve my teaching skills and NOT to assume that what came natural to me was NOT the same for everybody!
Again, I hope this helps you and everyone else on the Forum. If you need further help, just ask.
