Eugenio, as Simon says, almost all factory V-8 Ford air cleaners look identical. Panteras had the removable lid chromed as the main variant, and there were two orientations of the snorkel air intake. Early cars had it pointing towards the left-rear while later ones had it pointing toward the right-front (180 degrees different).
There is a protrusion inside the air cleaner body that orients the assembly off the carb top, but by cutting the little sheet-metal protrusion off the air cleaner body, any air cleaner can point either way. The snorkel indexes to a formed sheet metal 'choke-stove' & flex tube attached to a cylinder head around #8 exhaust (rt. side) or #1 (left side) as needed.
