Since we’re brainstorming, here’s my two cents.
I suggest creating a guide board approximately 3 inches wide and 18 inches in length. You'll want to pre-drill a centered hole using your Forstner bit. The board can be secured to the bed using double-sided carpet tape - just two strips, 4-6 inches long, should provide sufficient hold.
For precise positioning, you can utilize the existing bolt and offset washer to align the countersink. To ensure proper adhesion, simply apply your body weight by standing on it.
I recommend adding a rabbet cut to one end of the plank where it meets the bed. This will create space for inserting a pry bar or claw hammer when you need to remove it. While the adhesion will be quite strong, the plank should separate cleanly. Do remember to protect the bed surface when using any prying tools.
This technique comes from engineered floor installers. They use it to tighten tongue and groove joints in existing floors. One 2x4 with carpet tape adhered to the plank you want to move, then tap it with a hammer to close the joint. It can typically handle multiple joints without causing any damage or changing the tape.
As a precaution, I'd suggest testing the tape on a small area first to ensure it won't lift the finish.
