Crooked bed

[Blu64c10]

My truck bed never sat level, one corner always seemed to be lower then the rest. Upon removing my bed I noticed what seemed to be the cause of this. Of the two most rear bolts holding the bed on, one had some type of spacer and the other side did not. It seems to me that the side with the spacer is the correct side. Does anyone know if these are reproduced? What they are called? And where I can get a set?
