Wilmington NC here. I did the "Right Stuff" disc conversion on my 72. Only thing I didnt like was the caliper brackets seemed weak. But I got a great deal on the kit. If you shop the different companys offering a kit. You will find that most of them all are selling the same kit from the same manufacturer. Right Stuff Detailing co. Here is an example.
