shims between bed and frame

[atc82]

there was a post on here a long while ago that had a picture of a truck with shims or spacers on the right side of the frame where the bed bolts to. the right side of the bed of my truck is lower than the left it seems. Its not much, but it is enought to bug me everytime i look at it. When i tell some people, they don't even notice it. maybe i am just being anal about it. Do all trucks have this? is this (the shims) something from the factory? i have searched like mad and cannot find the post.

No I dont think it is factory Mine had the leen going on and I added the shims to get iit to sit level. Now if I could get the rearend to sit even under the truck side to side.
