a "914-6" sticker like they used on the GTs.
Did not right away recognize that sticker as "used on the GT's".
Did a quick review on the pbase 914-6 GT site and looked at many period photos. Did not see that marking on any cars.
Do what you wish - your car. But I don't think it was a factory GT thing.
