These are the correct fittings for the back deck of all Bugeyes. Four were factory mounted on every car.

If your car came with a short tonneau, you may also have a row of lift dot fittings along the back edge. But all cars used tenax fittings for tops and long tonneaus. These are machine thread fittings. 10/32 thread nuts are required to secure them, and not included.

Price is for one fitting.
