Chris,
So to answer your last sentence or two: Who is going to make that decision? A board that is comprised of several members already owning or having developed the narrow-track kits? The wide-track kits were made AFTER a ruling was made, not before and because the wide -track Manufacturers waited instead of rushing a kit to market in order to capture that specific market, they're now being told that they have to give up their investment in tooling & manufacturing costs. What about the drivers who bought the wide - track kits, they'd be illegal and now worthless after a considerable expense was made, so how is that fair? Does that really sound fair to punish those who waited on the decision and produced a product that is considered LEGAL at the time of MFG?
The OP said they can make narrow and wide-track kits, so do so and let's move on as the horse is out of the barn.
