U joints for 74 Dart Swinger 318

Rockauto is probably the cheapest route to get something decent. Summit or Jegs too. The problems with all those avenues tho is they wont differentiate the exact fit for your model......youll need to know which is which.

I would suggest a call to Dr Diff on the phone, and tell him what car you have and the details you do know (stock). He will hook you up, and the pricing is still very good.
