All of these visors from multiple vendors, including Dynacorn - producer of what are considered to be the highest quality reproduction sheet metal parts for a wide range of antique cars - are supposedly the "wrong" shape. Yet, they continue to be sold by respected vendors.

These visors are obviously being installed on hundreds or even thousands of other trucks.

The only common denominator here is your shop. I suspect they don't have the skill, desire, or knowledge to install them.
