Here are the "original" hay racks that the the first owner made for my truck in the 1940's. They are constructed of white oak stakes cut to the size of the stake pockets with pine 1x4's for rails. The short stiles next to the stakes are designed to retain the end sections of the rack and allow them to slide up and down. There is one steel rod at both the front and back, which, when tightened, stiffens the whole works and prevents the end sections from failing out of there grooves. I believe the inner partition is to keep animals from other things being transported. (Forgive the trucks lack of bumpers and running boards - they are off for repair.)
