Say good bye to a very nice car. Or help me fix it. It was worse in 84

oh snap!! (that's me not saying what I am really thinking) - let's start with - are YOU ok? for sure saddened to see this! there are plenty of Dusters out there for sale - it's a matter of finding the right one... as I am sure you know. So, pull the drive train and find a new car or what??
