No it's a 70 Z28, It may have been a car used by someone at the dealer or a family member, One of the old registration papers lists the original license date in october of 1970, but the car was built the end of may????????????
Anyway, I downloaded the form it downloads as two sheets,looks like a multiple use form, seems pretty confusing, i'm going to go back thru it over the week end. looks like section D is the one you need to think about a little bit.
Thanks for the help let me know how you filled out section "D" when you get it done.
