70 barracuda, single, and challenger, double, have different exhaust tips.
I'm no officianado, but I don't think N42 was available in cali.
Please, someone, correct me if I am wrong, but cali cars received turn downs even on dual exhaust. And a different rear valance, a valance like an aar.
Why chevy tips? Definitely wrong, but same style. I would say these, valance and tips were installed much later. Unless of course the dealership has mention of the tips/valance change alongside the ducktail spoiler and the hockey stripe.
Did the dealership install the hockey stripes and leave the v5x body side moldings on the car? I see the moldings were removed when the paint was updated. (still have those?)
The pan pictures of the transmission were asked for to verify it is an actual 727. The vin number stamping from the trans was asked for to verify that the trans actually came with the car originally.
It should indeed have a Y pipe system unless it was changed to upgrade to a true dual exhaust. Hamtramck style (the rest of America and canad..a).
Production numbers are subjective. There are no real recorded production numbers for this year mopar. All numbers are percentage based and not actual. The numbers may be close to correct, but there will not be any "correct" numbers found.
You may want to change your description as to the 7K tach since this has an 8K tach and 7k tach's were 72-74.
I appreciate your willingness to talk about the replies. Often times, most, folks list a car for sale and all us Cuda nuts dissect the car and the owner takes offense to "collectors" calling out what is not "correct" with the car. This is just something us collectors do and are not trying to offend a seller. Thanks for the openness.
About the paint, not surprising. Several folks have very different meanings to the term "survivor".
Your car is a stunning example of a barracuda.
If the dealer has listed the dealership changes I would still consider those to be part of the cars as built history. That is what the customer received from MOPAR, even if the factory did not install all of them. That provenance helps a bunch with those upgrades being survivor grade.
Since you have already posted the Monroney report and the BROADCAST sheet could you please post the fender tag, the vin tag and the door sticker? Those can help verify multiple items on the BROADCAST sheet.
