I have a 1969 matching numbers Z28 that has been professionally documented.
Not one single panel has been replaced (documented as well).
It has the original DZ 302 motor matching numbers.
Original transmission, original rear end, original glass.
Only 1 repaint and you can still see signs of original paint.
Whole car is original except carburetor and radiator are not original.
This is my personal car not some dealer car sitting on a lot.
I bought it from an 84 year old original owner who bought it fresh off the Sacramento Chevrolet lot in 1970.
We have original owners manual and original build sheet still located on the gas tank with pictures to prove. Original interior with no rips or tears. 70,000 original miles.
