Sold my car and no longer need. Bought in November last year and got them half-way through December, only used them to string up Christmas lights on the car. Have 2 sets of endcaps with keys, some of them have broken alignment (I assume) tabs but they go on just fine. Because of that, the company I bought them from sent me a second set where 3/4 of them are fine. Price is $400 OBO. Located in Cincinnati, OH, can meet locally or ship at buyer's expense.
