C-3 '72 Master Cylinder Broadcast Code

[Bill Lloyd #33481]

I have '72 Conv. When I purchased it I did the standard part number checks. The master cylinder (MC) checked correct for PN 5455509. I did not check the broadcast code at that time. I am about to rebuild the brake system. I have found that the broadcast code on the MC is ZC not DC. The JM indicates that this is correct for '72 calendar year cars. My car build date is Sept '71. Could this be correct? I believe that the MC is original to the car. Thanks

Bill, there should be a casting date on the MC. If the casting date is before the build date of the car, I would be inclined to assume the cylinder is original and restore it. Understand that the TIM&JG provides the best information available based on the somewhat limited observations.
