1966 plymouth valiant questions

OK guys, it looks like I have myself in a spot here.I know this is a 1 year only car. I have a '66 Valiant 200 that is in worse shape than I thought. I need to know if certain parts interchange from a 4 door to a 2 door. Will the front and rear seats from a 4 dr interchange with a 2 dr. Will front and rear glass interchange. Do they make front and rear glass rubbers. Does anybody know where to get a new floor pan for this car or will another floor pan from a earlier or later Valiant fit this car with modifications. All of this may decide whether this car can be saaved. Thanks for any info.
