Newbie with a jackknife bed question

Hi all,

Brand spanking new to the forum. Thanks in advance for your help.

Bought a pristine 1995 Jayco converted Ford Ecoline 1500 and have no clue how to put the jackknife bed extension together. It appears all the pieces are here. Can't find a link to anything that shows how to assemble. Does anyone know where to find instructions or an illustrated parts breakdown?

Thank you
