Built a simple belly pan in hopes to preemptively improve cooling when parked, crawling or stop-n-go traffic. Most all modern vehicles seal off cavitation or leakage paths around radiator. The 67-72 truck has some of this but areas for improvement. I also cut up the valance and changed the tight fitting bumper, so made the air return path underneath chassis worse. So biggest improvement for isolation was to block off this path with a short belly pan.
I used corrugated plastic sheet and a few fasteners. Cardboard template. Tapped 1/4-20 threads in frame. Used a short piece of tube as a crush sleeve to prevent crushing the material.

To prevent wind catching leading edge and ripping it off, I made it long enough to fit into bumper. This material is not rated for automotive use, 150 C, will see how it goes, or if it helps at all. Should catch all the leaking fluids and become a slimy mess itself soon enough. It does block access to things underneath, like alternator, so if no benefit will abandon or leave off in winter.
