What would you do.

"And to be honest Id much rather have a 67-68 valiant or a 70-72 duster." If that's really how your feeling, then maybe see if you can sell it and get what you really want. Sounds like your trying to justify keeping a car you really don't care for a lot, and wondering whether to put both time and money into it. Restoring these cars requires lots of work and patience, as well as money. At least get a car you really want if your going to spend both time and money on it.
