73 wiper motor
 

I'm looking for some info that would be helpful in replacing the wiper motor on a 73 coupe. mainly directions. The wiper motor would just keep on turning when the key was on, then yesterday it stopped. so I'm guessing I should replace it. Also is there anything else I should replace one I remove this thing. like the switch or rubber gromits. if this has any of those things. Any help would be greatly appreciated.
