I have a early produced 1969 z/28. VIN #124379L505424, 10D build date.
I have four AD I believe that are dated k18 9 20 AD (september 20, 1968).
And one YH wheel dated k10 5 18 YH (May 18 1970) (I'm not sure about this date).
Being the 2nd owner of the car, I believe that the previous owner who informed me
that he was road racing the car, had an accident, and had one wheel replaced. I dont see any
signs of an accident on the vehicle yet.
See pictures.
