So you would really have to know your codes on that build sheet to make the connection that this was a Z/28 right? I don't know the codes all that well, but i do see the PS under the front shock code which would be correct, and the paint code matches, so it is probably the same car. I don't see the VIN on that partial build sheet.
I guess the best thing to do is note down the Vin, because this car will be re-created at some point
