The "shiny tin box" is a pressure box for the carburetor - used to equalize the relative pressures inside and outside the carb. Otherwise, fuel would come gushing out the vents (and any other opening it could find) instead of through the jets.
Not sure what this one was made of, but you'll find a pressure box made of cast aluminum used on the handful of supercharged 304-V8 (R3) Avantis built by Studebaker. The supercharged 289-V8 (R2) Avantis got away without such a box by using a sealed carburetor (with a polished, cast aluminum bonnet and remote air cleaner), but I'd heard that Paxton simply found that the pressure box was less complicated/costly.
After Studebaker, Paxton supplied a supercharger setup, with pressure box, as optional equipment for Shelby's GT350 Mustang.
Getting back to the Panther, engine compartment space was clearly at a premium with the supercharger and pressure box. Perhaps the back corner was the only place left to put the air cleaner.
The 1957 Clippers featured a supercharger as standard euqipment and also used a pressure box - as seen in the attached illustration from the 1957 Packard-Clipper Chassis Parts Catalog. Though we don't (yet) have a '58 chassis parts book, here, I suspect the Packard Hawk also used a pressure box.
