HiLift Jack Bed Rail Mount

[Zeke555]

just occurred to me - I've got the Ford fold up bed extender mounted back there. So long as I am ok with it not folding flat against the side of the truck, these should still install just fine, don't you think?

I never had one of those but easy for you to check. When mounted they sit just inside the lip on the top of the bed rails. I would think you would have lots of clearance from them though from looking at pictures of how the fold back.
