Hi all,

I have a Bogen 3055 head that, with this product now available (http://www.manfrotto.com/product/0/M...ete_with_plate) I'd really like to swap out the big hex plate for the Arca system.

From the looks of the 3055, I should be able to remove the central screw (allen head) that's on-axis, directly below the center of where the hex plate sits and take the QR mechanism off of the top of the ball, but on mine, I can't get the screw to budge. Am I evaluating the head correctly? I don't want to force it and damage the head.
