Background: i am working on a 89 wagon for a friend, its not sparking
i have traced to problem to the distributor shaft ( the one that the rotor attaches to) is not turning at all i dont know about this engine at all. Is it gear driven from the exterior of the engine or does the shaft run into the engine? I'm going to buy a used distributor from a junkyard, what i need to know is could it have torn up a cam gear or something else that i will need to replace?

thanks
