I sure hope someone can help and as soon as possible as I've already wasted a week and a half trying to get this info. But PLEASE be sure your info is accurate!! I CAN'T mess this up!!! I'm trying to find out the size of the hole(s) I need to drill for the wood screw/old style (80's) Floyd bridge posts. Not the modern bushing/insert design but the old wood screws that go directly into the wood. I believe it involves two holes, one counterbored because it seems that the threads of the screw require one size and just under the head of the screw is a flat "collar" arear that looks to be a bit larger in diameter than the threads are. PLEASE...can anyone help with both the diameter and the depth of these holes? A step-by-step guide would be great, too. I've installed plenty of the bushing/insert type, but this is my first with the old style. Thanks!!!!!
