found method to install trailing opposing rivets was to place one on one side all the way in...pus the other side as mush as possible...do one pull on one side, then push other side in and set the rivet....then return to other side and complete that one
drilled out bottom trailing edge rivets riveted trailing edge per the description above drilling one rivet on the left flap created a larger hole...placed a rivet anyway for cosmetic purposes (some mechanical strength...placed another rivet beside it for the required mechanical strength (see iimage 1)
