I stand corrected. I pulled the bed off last night and realized that the lower bars dont run parallel to the ground. The bars are higher in the front than the back. The brackets used in the front are mounted to the underside of the frame rail nd the rear brackets are also mounted to the underside of the axle. I guess my question is do I need to raise the mounts on the axle side? Basically the mount on the axle would be more on the front than the bottom?

Thanks
