Another member cut slots through the thin section under the main rail to put in the flat bar & attached his u bolts to that. As long as you have rounded ends on the slit (drill 2 holes & cut between them) you wont have a stress concentration. But then again, you're an engineer so you're prob way ahead of me on that lol
this was me :lol:
i cut the slits for my roof top tent mounts. i wouldn't recommend it as one of the rails eventually cracked :rotfl:
