Only weld to the frame. Leave a little room for flex under body. I angled my 2 middle attachments so It created a little triangulation to take a hit front to back.

When I welded my sliders I used a piece of 1/2” plywood as a spacer between the shaved rockers and the sliders. The gap never changed and they took some pretty hard hits on big rocks.

Mine didn’t. I know some guys figured out that 1”x3”x0.120” wall box tubing fits inside the shaved rocker really well and welds to the bottom of the thicker “A” and “B” pillar supports well. I’ll do that on the next build.

I couldn't find any 1x3, so i got some 1x2 and 1x1 and welded them together and put them under the door sill for support. I made my sliders and cross supports out of 1/8" and it does flex a bit. I eventually want to tie my sliders into the roll cage mounts. That would keep the sliders away from the body and tie the cage to the frame.
I ran 2”x4”x 0.188” was rectangle tube on my sliders. Plenty of strength for supporting the entire weight without bending. I also used mine as air tanks and they never leaked. I also had the roll cage tied into the sliders below “A” and “B” pillars with polyurethane bushings to retain the body to frame flex.
