If the passenger side vin is also missing you are out of luck, no other vins will be on the car. You can compare the date codes found on the body to the vin that you find to somewhat tell if the vin matches the rest of the dates of the car. Many parts like the floor (under rear seat) and inner fender aprons have dates stamped on them when they were made. Like 7 25 3D decodes to July 25, 3rd shift at Dearborn plant. If you post the vin someone here can tell you the production date of the whole car and compare that date to the rest of the car dates. All the dates should be in the same month as the production date of the vin, probably all within two weeks of each other. That will give you an idea if the front clip and vin are original to the car. And actually if it is a 1967 you are in luck because they still have all the records for your car.
