ie. the cockpit of the F-82 is much further forward over the wing than the P-51s.
Actually the cockpit is in the same position as a P-51's cockpit, only it's raised as in the F-51H. I've found that from behind the spinner, the cockpit is the same distance on all P-51's and F-82's, as is the air intake opening for the radiator duct. Most of the F-82 fuselage is the same as the F-51H fuselage except where the rear fuselage was extended 67", and this extension is a continuation of the F-51H profile lines.
What I have found is this, when NA extended the F-51H fuselage 13", they not only extended the radiator duct, they moved the wing back that 13" too. Then when NA built the F-82, they moved the wing back another 12-13" (measurements from the rear of the spinner to the wing root leading edge) and on top of that the wing had a massive chord increase. BTW, the wing of the F-51H has a broader chord than the P-51H, it seems that the whole forward part from the main spar to the leading edge has a different chord.
So this is why the cockpit on a F-51H and the F-82 look like they are further forward, when in reality, just the wings have been moved backwards.
What I'm trying to find out now it whether the XP-51J had it's wing moved backwards, because this aircraft had the 13" rear fuselage extension too --
