Hey, good idea's. I’ve got a long needle nose pliers at work, I’ll give it a try. I’ll definitely be replacing them with stainless.
Will stainless steel and a corroded OEM fairing screw exhibit galling when exposed to moisture? If so - you may have a bigger mess than with the brass inserts.
A sure-fire way to cure this problem is to JB Weld the loose OEM brass inserts back into place, then use a dab of anti-seize on the screws. Search the old Tech Archives and you'll find a good bit of info relating to this repair.
