unfortunately it looks like I have a leaking rear main in the 70 Dart. I have a replacement Fel Pro seal to install. My Goal would be to change it in the car, without jacking up the motor, by pulling the steering linkage. Anyone have any tips, tricks, do's don'ts? I don't understand why it would be leaking, but I've confirmed it with an ultraviolet leak detection kit. It was assembled by the machine shop, so its all a mystery at this point.
