clip that holds the ''rotor'' on the distributer

I need one or at least know where to buy one. mine was flat and allowed my rotor to sort of flop around and through the timing off.
it a spring type clip found under the rotor inside the dis.cap it holds the rotor firm to the shaft by clipping around it
also known as ''Distributor Rotor Retainer Clips 65 66 67'' part number dz355



Ok I found one on e-bay for
412.00 lol but it will get me down the road the guy had more than one if any of you need one.
mine was worn out and it allowed the spark way to late on the rotor and cap.
