I have my old magnets for when I autocrossed in STX class. These were made locally in town by a business called 'One Stop Sticker Shop'. One for both sides of the car. The numbers are 747 STX. The stickers are blue lined with black on white magnets. I spent a pretty penny on these, so please make offers since I am unsure what these would sell for. They are in great shape and great quality. These have never come off my car on or off course when I had them on. Safe for 90+ mph.
