Im also of the opinion tha the wrong fenders were installed...But...It probably wasnt a mistake. Maybe there were no undrilled fenders on hand. And rather than fill the holes it was much easier to just install the emblems and call it a day. I think stuff like this happened all the time. Especially back then, when there wasnt as much scrutiny as you would find today.

As the cars were built they used the parts they were "supposed" to, but if there was a shortage then reasonable means were used to keep the line moving. In a case like this, installing a few extra emblems definitely falls under reasonable means...
