These are quality flaps but unlike the rear ones they use rivet nuts for the top two holes on each side and I've sanded down part of the top flange on each nut so they go all the way in due to the raised portion of the wing. Also, I found that the 23/64" hole was too big to get the rivet nut in properly and I used a small amount of JB Weld on each of them to hold them in place. Instead, I suggest using an 11/32 inch bit.
