Bow roller
 

So i bought a new anchor for my 38ec. Was talked into a number 4 serca excel. Anchor works great, but it doesnt fit on the bow roller, i need to lower the roller so the shank can fit though the opening.

Too lower the roller by extracting the pin I need to lift the entire bow roller system up. Question does anyone know how the nut on the bolts that hold bow roller setup down are attached. It going to be an real pain, if the nuts drops off into the bow of the boat somewhere, as i try to lift it up if it isnt retained somehow.
