Kevin -you have a '99, right? Is yours 4-cylinder or 6-cylinder. Anyway, I've had distributors out on both engines.
The rotor head be just about to start contacting/be under the #1 post.
Distributor out, lost my marks
I know where the #1 post is in the cap and can mark that on to the distributor body, then remove the cap and install the rotor pointing at the mark
I can set the engine up to #1 TDC
now what I need to know is, should the #1 post be directly in the center of the rotor head?
Or should the rotor head be just about to start contacting the #1 post?
I know that I can just adjust the distributor accordingly either way as long as it's in the general region of the #1 post until I achieve the correct ignition timing with my gun,
BUT I want it to be as close as possible because I'll be firing up the motor for the first time after being torn down and the new cams need to go through the break in procedure by running the RPM at 2k (immediately) for 30 minutes. Any time idling during the break in can damage my cams
So I can't be screwing around with the timing light during the cam break in

On my daughter's '98 Pathfinder with same V6 engine, the distributor hold-down bolt is NOT in the center of the distributor groove when timed correctly, it's near the end.
Yeah, now I remember: on my daughter's '98 Pathfinder - she bought an aftermarket distributor for $82 - I had to "lengthen" the slot about 1/16th of an inch to be able to reach the factory timing.Same with my '01 Frontier: IIRC the slot on the distrib is all the way towards the windshield, so the bolt itself is located in a position where the distributor could only be moved counterclockwise towards the front of the truck.
You could remove #1 spark plug and use a plastic drinking straw to confirm your engine was at TDC for #1 and not a full crankshaft revolution "off" when the pulley marks line up. Do NOT use a pencil to do this !!!
