Wasn't hard to find it on the web.

As mentioned the body lines will be an issue, but this guy made to save it I guess using a Charger door skin on the front doors frame.



Now, installing the door skin in a 2 doors Coronet... well, will be dealing to the next body line: quarter. 4 doors could be easier since the next door allow a line breaking between the Charger and the Coronet body lines.

more pics here, with sun over the body showing a bit more the lines matching job.
