I got the new sliders all finished and mounted. I bolted them on, but I think I'm going to get them welded to the frame on the bottom just for a bit of extra strength. My driveway is on a hill, so I didn't do the hi-lift jack test for pics, but I'll take one next time i'm resting on one of them on a trail.
I'm super happy with them, we used the stock holes for the front and back legs, so i only had to drill 2 new holes for the middle leg. Other then being black (instead of silver), they look and work like the stock running boards/steps... just stronger now.
Thanks everyone for the tips.
