Fender Tag Advice If You Please...
As stated you have to find the broadcast sheet if no fender tag is present. If you do find the BC sheet verify it matches the car. If all is good you can contact datatags and see if they will create you a new fender tag with the data you have. You will need to supply them with photos of vin, body tags and broadcast sheet with options. If you can not supply that then it is a no go. They will not build tags for dream cars to protect the hobby.
If it were a 67 or earlier you can order a build card from Chrysler Historical. For 68 up you can not as there was a fire in the archive and the water damage was extensive so that why you can only get up to 67.
