Mallory ignition system

[slats]

I am using a series 47 Mallory distributer. I have a # 208 distributer cap, which calls for a # 305 rotor. I have gone through 3 rotors. All three were defective from the factory. I talked to a tech from Mallory who admitted that they had produced a bad batch of the 305 rotors. I explained to him that I had about $50.00 Invested in these defective rotors and asked him if Mallory could send me a rotor. They sent me 2, and they looked exactly like the ones that didn,t work. I called the tech at Mallory again and he told me I had to file the comtact on the rotor and then bend it, etc...etc.. I can,t believe they are still sending out this defective piece. Has this problem happened to anyone else? and if so how did you fix the rotor?
