Rare M Code 'cuda (?)

Know your last question was aimed at BB-Dave, and dont know if you are only talking of M code fastbacks, but I can speak with authority as to 1 original 69 notch with black vinyl top and 318. Bought it from original owners son once she passed around 2006, had only 32K on tbe clock, always garaged, looked like new and still had that new car smell due to such great loving care.
Very cool!!! Yep, all Barracuda's from Slant Six to 440. How many had "Wigs" in '69?
