Just drill and tap the hole for the screw...not too deep though, just enough to set it (set screw) back flush with the housing. Make sure to cover the bearing with a damp cloth or something to prevent shavings from getting in those nice bearings! All this mod does is keep your pump from slinging oily grime on your 200HP LCE motor, so if your engine pees out oil anyway, then it may not be worth it. Hope this helps!
