A teenagers "insert cool project name here"
How about lucky, as in lucky you haven't totaled it. That's a nice duster you have. If the motor, tranny and brakes are good, it might be time for an 8 3/4 rear end, yes I know there spendy, but there a lot stronger(my opinion) and easier to work on. Good luck on your car, Keep it between to ditches and the rubber side down.
