Hi everyone, Have a 1964 Pontiac gto and was wondering if anyone knows how to check the vin numbers to see if it is an original gto from the maufacturer or if it was made into a gto with a kit. I was told that some of these cars were pre-slated by the manufacturer and the dealers did the switch-over from a lemans-tempest to a gto. We are new to this, but it is something my boyfriend has always wanted to do. I am trying to help him research this but have not had much luck myself. HELP!!!!!!!!!
