Gotta be the Minnesota based CAF P51C.
When I was 15 or so back in the mid 70s that bird was unrestored and the fuselage and wings were leaning against the hanger of Jack Sandberg in Crystal Minnesota where i took flying lessons. I snuck into the cockpit from underneath one day and vividly remember reading that Data plate on the right edge of the cockpit saying it was built in Dallas, Texas. I spent many a day trying to figure out how I was going to haul away the pieces of that 51 without being seen

It didnt' look quite that clean back in 1975
