Now that the liner is settled, back to beating the dead horse on rear cross cut/bumper/wings.
If I cut here
And fab some sort of cross member/roll pan to align with the curvature of the rear door, gain a few inches that was impacting departure angle, but loosing attachment points for wings.
Also, taper the bottom of the frame rails to be more in line with the lower quarter like this, an effort to minimize dragging the frame,
Would plate ends and bottom of rails, fab new body mounts, or reinforce what's left after tapered cut, but doesn't leave room to attach quarter protection without negating the benefits, actual or perceived, off cutting and tapering. (yeah, that's Denglish

)
Still contemplating the aft frame mounted sway bar and wondering if I could bore 1 1/4" holes through the frame rails where the sway bar locates (~22" from centerline of axle), run sch 40 ( think 3/16" wall, but unconfirmed) through rails and weld (possibly plate the attachment point on the inner rail) that'd alt as as additional rear cross member.
That's semi-sorta irrelevant to the pertinent question of wing support, but throwing it out now, since suited up for flaming.
Not knowing how much the body flexes, asking for input regarding boring holes through the lower quarters and running wing supports back to frame, similar to
Addressing water tightness on interior of panel with sealant, or welding sheet metal in the diameter if the hole, either way.
Could run tube back to frame and weld direct, and know that when it gets bent, it'll be a major PITA to fix.
Comments or suggestion?
Edited: and yes, my twelve year old did show me how to use Scribble Lite, finally.
