To all of you who were following the thread on the distributor orientation,
mine was 180 degrees off. Last night I removed it and put the gear/shaft
thingie back in after rotating it 180 degrees. Fred is right. The Clymer
manual text is wrong (I followed it carefully when I first put this
together). So follow the picture (correct) or do the opposite of the text.

Adam,
It doesn't really matter. As I said in an earlier post today, the only way
to tell whether #1 on the distributor is towards the radiator or towards the
firewall is to match the orientation of the valves at 0 degrees TDC (end of
compression stroke before firing).
If you look at the Clymers manual (copy of Nissan's) in the 2000 engine
section, they describe installing the thingee (distributor drive gear). The
text says 11:25 position for the off-center slot, with the smaller
semi-circle MUST be placed toward the FRONT. The picture (Fig EM-128) shows
the LARGER semi-circle towards the FRONT. Even they were confused!
