Those who have one or installed one will know what I'm talking about. The two ends are different on the shaft, which end goes in the oil pump? I assume the shorter side without the point? And also, the little washer thing that comes with it to keep it from pulling out when you remove the distributor. How do you get it on the shaft? It's too small and I don't wanna force it on if I don't have to. Also, which way should the cup side be facing, up or down? Sorry if it's confusing, thanks guys.
