Help... Vin #'s dont match

Those package tray VIN numbers have the correct format?

Looks kinda odd to me.

VX29J2B123456 is the format
VX29J2B2423383 has too many characters

Even if the 4 is a A it still doesn't fit.

( I know VX is not a valid body style and a J code Hemi was not available in a 72 A body- they're for illustration purposes)
