Got this one of the bay, and apparently those "heads" to the left and right of the saddles, are screws that goes into some kind of pretty big nuts (not any of them attached to the bridge though).

Am I supposed to drill giant holes in the body for sinking down those nuts or what?
Really does feel like I ordered the wrong piece, though this bridge looks exactly the way I'd love a bridge to be on my project here ...
