He added that the components of the fuselage all come from different manufacturers and are not all the same shape.

No problem. It’s just stressed tensile strength.
Makes it fly more better. lol
Having worked for a Boeing supplier, I can attest that at one time their tolerances on some machined parts were quite generous (+/- .020, +/- .030 on rivet hole locations) Don’t know if thats the case now, but yeah, I can see every construction being different. For the record, most stuff I do now is +/- .005 or less, and its not aircraft related, thank heavens.
