I'm gonna' go out on a limb and say this is Art Stagg's tall-tail (NACA tail) D in a hangar at Oakland circa-1984. Stagg's airplane was later painted in the popular yellow forward cowl/spinner with blue scalloped top surfaces, D-day stripes, a-la the "Lou IV" WWII scheme.
This P-51 is unknown to us as well. I have a picture of 44-74506 from Dax Roman that is taken from the same hangar. I don't know the date, but it is in the previous red noser paint scheme at the time which dates it no earlier than '92.
I can give an assumption, but no proof:
This ship could either be
44-84864, NACA-126, which became N4223A and is flying today, or
44-84900, NACA-127, which became N51YZ and is restored in NACA-colours.
Both a/c had 'high' tails when surplused.
My guess is that it is 44-84900.
Guess again!! It is serial no. 44-74976 and it flies on the airshow circuit as OBSESSION. I bought it from the Johnson family in 1986. I have owned it for twenty five years and fly it about 25-50 hours a year and still loving it.

I met you not too long ago at the spruce creek fly-in with my buddy Jackson. I am not sure if this message will reach you but I was wondering if you could send me an email at email@example.com. It is about getting Jackson a flight in Obsession. Please send me an email and hopefully we can work something out.
Jeff, My name is Brian Moore. I backed into your car at the hobby shop in Archdale nc 2016. I see the claim has been paid. You mentioned that it is hard to find people to fly control line with.
