Nice to hear of a 440 'cuda notch sighting back in the '90s !!! I run the only '69 440 'cuda registry and will look thru my records for a yellow notch in that area!!!! I have over 100 cars in the registry and several notches.............
I knew a guy around here in the early 80's that had an original 68 Dart GSS with 45 k original miles that was yellow. That's not a typo, it was a GSS, not GTS... An original Mr. Norm car... He walked me through how Mr. Norm converted the GTS into a GSS when I first saw his car.
His nephew used to cruise Dukes Drive In on the south side here with an original green 69 Barracuda fastback M-code 440 car.
I remember his uncle telling me that it had headers on it. Every time his nephew pulled the engine to work on it, he would always buy a new starter and install it because the headers were so tight with the 440 in there, that it would cook the starters from all the heat and they would burn them out often. So it was more convenient to change the starter every time the engine was out than to try installing the starter with everything in the engine compartment... They were only $30 -$35 for a starter then...
I've lost track of them after going away for school and work...
Do you have any listings for a Green 69 fastback near Chicago???
