What is this part?, Do members of the world run without it...any problems? Options

This piece of plastic was mounted on the rear edge of the floorpan at the engine bay on the drivers side. The one on the passenger side mush have fallen off due to rust.

Not looking for a concourse car here, but don't want to omit any pieces that will cause me problems down the road.

Anyone run their car without these plastic flaps?

The pair of these parts introduces turbulence to the air flow under the car, aiding engine cooling. You should have them. The Cap'n

These air flaps/diverters were added in the 73 MY due to the engines running hotter with leaner mixtures & higher smog controls, as well as the 70-72 standing problems with hot egine bays causing vapor lock (fuel pump relocation under the fuel tank in F trunk for 75-76 MY was another "factory fix", as well as a service bulletin to relocate the 70-74 FP up under the steering rack at the front pan/firewall next to the tunnell access hole).

I would be interested in seeing this "service bulletin'. I worked at a dealership and took all the available factory training classes through 1974, and I've never seen or heard of it. It's not in the TSB books I have, either.
