Remember when installing the distributor to mark it on the top, of the rotor pointing to #1, same as the dots on the shaft.
This way you will be lined up when the distributor is all the way in.
The rotor button will rotate around once it contacts the cam gear and will get you off pointing to #1.
The rotor has to be pointing a good bit before #1 to end up there once installed.
If you follw the method in the link provided you will have no problems.
I did a 90 loyale as my first timing belt change ever with no problems.
I'm no gear head just a do it yourselfer who basically changes his own oil.
BTW, #1 cylinder is passenger side front I believe.
