Center Caps for 4 lug Centerlines

My pleasure. The first version caps are extremely rare. I haven't seen any on a car in at least ten years. When they first came out, centerlines were very expensive. They didn't become popular till the racers started using them in place of the fragile supertricks
Edit: found an ebay listing for four new four lug autodrag caps,like yours pictured. $65. From lugnutking. Googled c-70 centerline caps.
