Dave, I have a set on my 63 LeBaron and I am very satisfied. I installed them myself and there was hardly any balancing requied, which indicates good quality to me. As far as how long they will wear, I cannot say and probably will have the car sold before that happens anyway. They look great also. Thomas Gunnari 59 Crown 2D 63 Crown 4D 63 LeBaron 65 Crown 4D
