I'm in the process of restoring my 1980 Fleetwood Brougham and the previous owner got a ziebtart coating, but apparently waited to long to do so, because they trapped more rust than they prevented. My rear driver’s side door is rusted beyond repair, and my question is this. Would a door from a 1981 Fleetwood Brougham fit onto my 1980? Also, would any other years fit my vehicle? It's probably a simple answer, but I'd hate to waste the money, and then find out the door doesn't fit. Thanks.
