'66 Dart valance panel

You may be right. I just looked at a couple of '66 parts cars on a website. Someone could have put a '65 bumper on it. Which could explain the excessive space below the bumper. I notices the '65's have the body kind of molded around the bumper where on my car the body cuts off flat at the bumper. I will post some pictures ASAP and you can advise me. Someone has put the long shackles on the leaf springs which makes it all the more noticeable. Thanks for the advise and I will take som pictures so that you can see more of what I'm talking about. I'm keeping this car stock as its has a pretty clean body and fairly low miles.(41,000) I'll post the pictures ASAP. Likely tomorrow. Thanks to everyone for their help.
