My truglo site did have actually 3 sets of holes, but the mounting screws for the quiver were too long and didn't have nuts. Also the site didnt' have threads to receive the screws. So, I used two quiver screws through both the quiver mount, and the site bracket, and into the site mounting holes on the riser. The quiver is ugly as hell, but it holds the arrows, so it does it's job. I'll try to get some pics posted. maybe tomarrow.
