Hate to tell you guys,but Crossram 1969 is absolutely correct. There is a guy named Troy Acton, who purchased a 70 Stage 1 GS from a guy that apparently had the same thing done to it. He asked me to help out with some cowl tag decoding and the car was painted 1 color(original to the car) and the tag revealed another color. Then,when he looked even deeper,the car was an A/C car and the original buildsheet options for the VIN was a non A/C car. The Indiana State Police even went as far as taking the body up off the frame to only see the frame numbers were not the same as the VIN numbers. On an A body GM car, the frame is stamped in a few places and the bodies are generally stamped in a couple places as well with the last numbers of the VIN. I know where these are(but don't ask me to disclose) and helped Troy get to the bottom of it. In the end,the seller was taken to court and had not only to pay him back,but also had to retain possesion of the car. The bad thing is,its now on record, and the State Police even took cutters and took the VIN tag leaving a big open hole in the dash. There was alot of bad press over it,but in the end even though Troy didn't do a thorough enough job checking this car out,it was still irresponsibility on the sellers behalf that was brought out.He should have done the same as Troy,unless he knew all of the illegal work. My Point to Lowdown is if you switched the tags or had info regarding it and tried to make a buck on someone unsuspecting...YOU are a scumbag and should be prosecuted to the fullest,If you were an innocent party..I'd be contacting my lawyer to get a refund of money since you were screwed too.
