Rod end mounting

I Have saw soom posts on here about rod end mounting width saying that most trucks 4-link mounts are 2" apart potentially causing the rod end to bind and break. I will be running the standard 1 1/4x1 4 link rod ends, what is the minimum width between mounts so the rod end won't bind? How far in from the end of the mount should the hole be? I have saw some trucks that only have a 1/2" from the edge of the hole to the end of the mount, seems like it could be a week spot. But if the hole is too far in it will cause binding issues as well, where is the sweet spot?
