I don't have any additional close ups of the area where they mount to the slider. The square body of slider was drilled and tapped on the end, and on the inboard side near to the end. They are 2 inboard bolts and 2 end bolts where each bar attaches to each slider. They are reasonably stout. The customer has yet to bend them, or snap off either mounting end. I'm sure serious rock crawling could damage them, but I would expect them to hold up to anything that someone is going to do with a full-bodied truck. They are not as strong as a frame-mounted slider for sure, due to the lack of gussets/legs coming off of the frame etc.
