Those new GOAT Shell designs are designed to take that lanyard bushing frustration away and make that swap to an OG as easy as possible!
Your set will have come with two sets of screws, both a black and silver set to match your existing hardware finish.  Each set includes two longer screws (and one short screw) that will be used to get thoes new GOATs installed.  You will use the pocket clip holes to complete the build.
With the belly of your knife pointing toward you...the two longer screws should be installed in "top" screw hole and the screw hole.  If you desire, you can use a bit of locktite to keep those screws tight and secure!  However, you should NOT need to overtighten those screws to find a secure fit, and doing so can cause damage to the screws and the scales by stripping them!  The last short screw is for the "bottom" hole (closest to you), and is used only for securing the pocket clip and does not impact installation.
