Your car was built at the Norwood Ohio plant before the X-codes were being used. They started using the X-codes on the second week of January '69 but your build week is too early. That means we can't tell from the trim tag if it was originally equipped with the style trim group. You might find a crayon marking on the rear bulkhead behind the back seat. If you have the seat out you can look for a crayon marking on the passenger side rear bulkhead of the car. You may see "X-1" written there (or some other letter related to the interior color followed by -1) and that would tell you the style trim option was original to the car.
