i have a few guitars with the allparts one screwed in. that one holds all 4
allen wrenches. much better than the one where the
allen wrench is a "T" type tool. That ones tends to fall out, and you only have 2 allen wrenches. i usually will cut the screws shorter, or just use shorter screws. no problems at all. the holes from the tuning pegs and locking nut are much bigger, so i wouldn't worry about 2 tiny screws. but, if you can double-sided tape it, all the better.
www.allparts.com if you wanna check it out. but i don't know if they deliver to australia. :-).
