No offense taken! It wouldn't surprise me if Alfa did things differently from one week to the next.Please do not take offense to this but sales brochures can certainly be misleading and/or wrong. Being that I own two 1971 spiders, I can assure you without any doubt that these are the correct kind of seat belts and that the labels are on each side as to provide symmetry when both buckles are buckled. See photo. It makes sense once seen.
