Wiper system

First time ever working on a Mopar.:banghead: I could use some HELP please. I have 73 Dart Swinger. A lot of work has been done already. The wiper motor was shot. Wires were striped so I pulled it off and found that nothing was connected to the motor. The linkage arms weren't connected just laying in the dash.:banghead: Not even connected to the wiper arms.:banghead: I got a new wiper motor new seals and rubber for wiper arms. My problem is. I don't know if they are the right ones for the Dart. One has a slight bend at one end. Dose the motor turn in a 360* a 180* or 90* I haven't a clue. :scratch: I will wait for a reply before I put power to the motor.
