I know it is preferable to deal in facts when it comes to the S30, but when an anomaly such as this is found I can’t help but try to find the reason for it. This is pure speculation on my part, but I would like to relay my theory. Please feel free to tell me what you think. This theory is based on the premise that it was acceptable to upgrade a vehicle when a mistake had been made but not acceptable to downgrade when a mistake had been made. This is a practice that was in effect during this time period in the assembly plants I was involved with. It was just good economic sense. For example, if a wrong part was installed and the cost to change it was more than the difference of the upgraded part and estimated labor cost it was common practice to allow the upgrade. Everyone knew what upgrades were acceptable and what ones weren’t. I think these longer luggage straps are the result of a mistake made during their assembly, but deemed to be acceptable for use. It could not have been a mistake that simply slipped by because the straps are used in pairs. Nobody has found a car with only 1 long strap. I am visualizing the work station where these luggage straps were assembled. The operator would be seated at a sewing machine, a hot knife cutting fixture would be used and all needed parts would be at arms length. The parts would include: 2 – end brackets 1 – large buckle piece 1 – small buckle piece 1 – plastic sleeve 1 – length of banding (the reason for 1 piece of banding instead of two will become apparent) The bench/work station must have had a method of measuring incorporated in the design to allow for consistency in the length of the straps. I am picturing a jig where after the strap end has been threaded through the end bracket and sewn, it is hooked by the screw holes in the end bracket and stretched out to the hot knife cutting fixture. After being cut this end would be folded over and sewn. After threading on the plastic sleeve this strap section is complete, ready to be threaded onto the buckle of the second piece after it is sewn onto the other end bracket and the two buckle pieces. A seemingly simple operation, but with the boredom of these type of jobs, workers trying to meet a quota, the interruption of work because of scheduled breaks, shift changes, or any number of reasons, mistakes are made. In this case, it would be as easy as picking up the longer strap that has been cut to size and sewing the buckle pieces on by mistake. Whoops…put that one aside until we have a set, because it’s bound to happen again. It would have been a waste of man hours to interupt the work flow, correct the piece and dispose of the remmants. This is why I don’t think you will find the longer straps in any manuals, brochures, or offered as an option. I think they are just simple mistakes that were allowed to be used early on in the S30 build. Edit - One thing I forgot to mention is, if the length needed for a normal short piece is removed from the long one, the piece left over is exactly the length of one of these oddball long straps. Coincidence?
