Of course, all the drivertrain, suspension, etc parts were interchangeable... but I'm specifically referring to the wings, fenders, fender scoops, rear windows, A pillar aero, and fender legs
so, having told you what that source had to say, since I don't just make shit up - I relate to you what I find other people have said, and then I give you a link to them so you can tell THEM what they don't know, and have gotten wrong, I also will show you what was just sent to me, that the nosecones are different, though possibly still interchangeable - but the Super Bird has a peaked center.
This then reinforces what I read in Muscle Car Review, https://justacarguy.blogspot.com/2019/01/unrestored-daytona-with-only-20904.html that only the flip up headlights are the same parts.
Notice, I'm still telling you what I found, and what source. Again, I'm not making this up, I'm telling you something that I've found other people stating, and letting you go tell them what you think about it.
and now with this Super Bird image to compare to the blue Daytona above, it's easy to see that the Bird's beak is peaked in the top center.
And the grill is not the same in the different nose cones. Are they interchangeable? I don't know. Will they bolt onto the wrong car? I doubt anyone has tried to find out.
I think that brings this issue to a close, and unless anyone has a side by side comparison of the bolt patterns of the Daytona and Super Bird nosecones, there isn't anything else to say about their interchangeability... if they can be swapped probably isn't anything anyone will have an article or first hand experience with
