Jerry, thanks for the reply. I had read that on a question about a 67 but never thought it would be the same for a 69. They must have put the doors on after the fact. I take it the stripe was a option then?
The D90 stripe was painted on the Chevrolet front sheet metal in Chevrolet's Paint Shop, and the tail piece on the door was a decal, installed on the Final Line, after the hood and fenders were installed and fitted. If Fisher Body had painted the tail piece on the door, it's unlikely that it would have aligned correctly with its mating stripe on the Chevrolet-painted fender - that's why it was a decal.
