purchased a new black handle and some extra screws because my handle is loose because a screw head broke off leaving threaded point in the black plastic. BUT the black handle matches perfectly but clip screwed to back side of handle for mounting looks nothing like what mine has, so I don’t think i can use it and am a little hesitant to throw more money at it ordering more parts when I cannot tell if it will be compatible to the flat washer with a large raised phillips screwhead still in my door.My old handle pressed flat to secured screwheads in large circle then the handle slid down firmly to lock into place.
I forgot to mention my serial number:52367328LE
Here are the parts

Without being there it is hard to understand exactly what the problem is.
Take a look at section 10.
If you click on the pictures of the handle and mount parts a new page will open with better/more views and also a Q&A section.
Perhaps this will help you.
