Questions on Replacing Bed Wood?

The washered bolts should be what hold the bed to the frame.

Most of us don't have the option of three choices for lifting the bed off and do what we have to do. For me with my 71 that will be lift the front with my gantry and chain hoist and lift the back with my cherry picker, roll the truck out from under it and set it on a small trailer I have to move it out of the way if I am not ready to work on it. I've changed a couple that way in the past but for you the safest may be using the two post and actually lifting with the arms above the bed rather than under it. The only rub there is that if you don't have something to set it on that you can roll it around on you have the hoist tied up.
