Oh, you planned that?
I think it's a good design mod.
No, I didn't, it just happened from not being careful.
The better option IMO if you are having these built is that guys now use triangular gussets over at the foot attaching point to the frame. And the foot should probably be 1/4" (won't add any real weight), whereas my foot is 3/16ths plate.
But if you want the slider right up to the body like I did, you certainly can do the bump stop and bolting. I also had to cut off most of the underneath fender mount and redo that since it was in the way of getting the slider all the way up next to the body.
