I have a 69 LeBaron also & those areas of rust are a little more obvious on my car. I have a new top, but fear this will be a costly job to have done correctly.Depending on how bad the rust is, it shouldn't actually be all that costly. Most of the effort in bodywork goes into sanding and smoothing so that it will look good once it's painted -- since this area of rust will be hidden under the vinyl top, making it look perfect is not an issue.
