It is a sales blank order, yes someone screwed up at the dealership and forgot to check off radio I am guessing. There is no R code on fender tag and build sheet in the radio section is very hard to read from a set spring. I just bought this car and it has a radio in it which I will not take out. I am betting the dealership added it once it showed up. I am hoping to track down original owner to find out if it was in the car when bought new as he will be the only one that knows for sure how it left the dealership. I just wanted to have the correct part as this car is a complete survivor with only 42,000 miles on it. What you are looking at is original paint, chrome and bright work. It is an incredible car.
