Now you're now just grasping at straws. I orginally told you the sliders would probably overlap by 50%. You insisted that was wrong, I got you a picture of a standard slider and took the time to go out and take a picture of this setup and proved you wrong. They would indeed overlap by 50% and considering the average slider is 2" wide there is a whole whopping 1" difference in contact area height. That incredibly huge difference you mentioned earlier has come down to 1" but hey, I'm sure that's enough to cause to some cataclysmal failure too eh?
As far as the "bracket should" be and "notice void" statements...get it through your head, the bracket DOES continue and mount back there.
Look at the first pictures on the web page and try to comprehend, I didn't cut anything off and the 5/16" plate didn't just disappear at mounting time.
About the only thing you've said so far that might have made sense is the leverage deal IF the pinch bolt was the only thing holding that right bracket in place...it isn't and it's not the main stress carrier.
And why did you write "watch this line" for something that is nowhere near the bracket and has nothing to do with anything? More added drama?
