For the 57' Chevy Guys?

[SLO_Z28]

Like I said, X's over the end of a VIN are usually a prototype car. I happen to know where the prototype C5 Z06 is, and the last of the VIN is XXXXXX. Back when I worked for chevy we beat up some C6 prototypes at las vegas speedway, same thing, VIN of XXXXXX.

Post pics, im curious if its a re-stamp.
