He may believe that, but in actuality, they did the radio antenna into the early 93s, so there were more than 100 done. This is the likely answer, but there are so many misconceptions about the early years, that he may believe it was something like air conditioning not being offered. It was not offered from the factory until later, but take a shot and see what he says. The antenna is often thought of as only a 92 option ( but, they built over 100 92s ) , but there was a small number of 93s with the antenna mounted to the rear quarter panel. Good luck and see what he says.
