Has anybody checked their axle straightness after installing these? That's been my biggest concern about it, is pulling some arch into the tubes after getting enough heat into them to join the 3/16 plate to the tube, and then not being able to straighten it back since the other brackets would preclude welding a similar bead diametrically opposed to the original. I dealt with the weld shrinkage fiasco when I welded a receiver tube into my rear bumper and now I consider that potential in every project.
