My daughter in law has a late 70s 3/4 ton Dodge pickup truck that I think has a Dana in it. Is there a financial advantage in converting it to fit a Dart vs just buying a new setup?
Financial advantage to a new one, no. One could convert an old one much cheaper, if you didn't have to farm out the labor. Advantages of the Strange S60 are lighter weight, and you eliminate the side shims because they have adjusters.
