As I said, some distributor tangs are not the same, so this method only applies to "ones that are." Are what? Well "aligned with the way to which the factory refers." "How do you know?" You don't until you drop the dist in, and then it's too late.
Why screw with it. Just put the thing in, see where it points, and drop the no1 wire in that hole.
You CAN walk the gear "over to where it belongs" with a screwdriver if you have to.
