Began disassembling the elevators, final deburring and dimpling parts as I go.
The image shows the left and right stiftener plates - the two nut plates at the top of each stiftener are added for the new fairings. These represent the only mounting hardware added to support the fairings, The other two screws holding the fairings (there are four screws per fairing) are existing cover=plate screws that will now be serving double-duty.
