Yes the vin tag on the dash should match. There should also be a vin in the driver door right buy ther door latch. There may also be a parshall o the rad support and rear package try. I don't know where exactly they would be though. Sorry I am sure some one will chime in with more info.
On an E-body, the VIN will be on the dash tag, the DS door sticker, the fender tag, the rad support and the DS cowl. The numbers on the rad support and cowl are just the last 6 digits of the VIN.
