I divide the PF into six sections: 1) upper left, 2)upper right, 3)mid left, etc to 6)lower right. Take pics of each section in order from various angles. Store the parts in labeled/numbered zip lock bags. Found this method easier and takes less space than laying them out as they come off. For a PF swap I leave the posts on until I am ready to move them to the new PF. I use an iPad for pic reference when/if I need to reference them.
