1. Is there a special character in the VIN denoting the Express model? The 5th digit of the VIN should be an "S"
2. Did they still come with fender tags that year and if so, where was it? There is a tag in the door jamb, and then an equipment tag on the core support as well as normally an equipment decal under the hood.
3. Broadcast sheet location the same for the trucks as the cars like under the seats or behind the dash? I have found them under the carpet and in under and in the back of the seats
4. VIN stamped on any place on the body like the early Mopars had that I should look for? (Radiator support, cowl, etc) I believe the VIN is on the cowl but forget where it will also be on the frame on the drivers side around the door area.http://lilreddad.com/Misc.html
