Twolate, glad to hear that you are in touch with your feelings.
I came across it trying to research G limits. I didn't find my answer there but did find it somewhere else.
.......the P38 and P-51 were designed to 8g limit and 12g ultimate but in each case that was linked to a specific gross weight. For the Mustang, limit load of 8G applied to 8,000 pound gross weight which was middle range for an XP-51 and P-51A. By the time the P-51D was operational a limit load for 10,000 pounds Gross weight was 6.4 G (8 x 8000/10,000).
