First 1967 383 installed in a Barracuda

sean hasn't been around since 2018, and I never saw the VIN or buildcard, car has no fender tag, but if the VIN and rad/trunk #s are correct/original to the car, this would be the only '67 383 car with a Shipping Order Number prior to 3/1/67, (2/27/67).
FYI: 2/27/67 was a Monday.

BUT (big but) nothing concrete, no pics of #s, and more importantly for any car the SO# is just a Scheduled Shipping date, not the actual Shipped Date, and neither is the actual production date.

So his car could have been scheduled, along with a whole stack of other 383 cars, for Monday the 27th, and they were all pushed to Wed. 3/1 because of this or that, or the other.

My car was scheduled for Wed. 5/31, it was actually shipped on Fri. 5/26, and the engine is stamped 5/23 of '67, so when was it 'built'?
It could have been sitting in the Hamtramck parking lot for a few days, which is possible, but then again it was ordered/sold out of Illinois, but then again again sometimes shipping next door takes longer than shipping across the country.

Since '67 cars have buildcards, I would stick to the actual Shipped Date.
