How many CURRENT owners of real '74 360 Duster 4 speed cars on here?

That's not the news I really wanted to hear.Do you think these cars will ever be worth anything compared to the 340 cars?Or if they will ever reproduce the interior plastic pieces for 73 & up models?I would love to completely restore mine,but if it is going to cost more than it will ever be worth,I'm not sure if I want to put in the effort.My plan was to buy them,restore them,enjoy them and then sell them when it came time for me to retire(about 20 years from now,no kids or family to leave them to).
