[69LM1]

Once a Z-28, always a Z-28. You could go to the local state police (in most states, check yours) and have them reissue a new VIn, however, it will not be a chevrolet 124379 vin.
If someone out there still certifies Z's then with that paperwork you might be ok?

Of course, it is still a vintage Z-28 made in to a 1/4mle Racecar, and you can always restore it to those specs.
