At the very bottom of the page in YELLOW.
With a flashlight and mirror, it is NOT that hard to see the apex seal pass by the sparkplug holes.
Put a piece of masking tape on the aft flange of the pulley so you can see the marks your going to make.
The only alteration I'd make to his method is: When sighting the apex seal in the LEAD hole (bottom hole), don't center the apex seal in the sparkplug opening, but keep rotating the pulley til the apex seal is resting in the bottom of the sparkplug hole. THEN make a mark on the masking tape.
As for the TRAIL hole, center the apex seal in the hole then make the pencil mark on the masking tape.
For any accuracy at all, you almost have to use a flexible scale measuring in 100th's, at least.
Anyway, TDC should be b/t those two marks. And, I'd suspect that once you make those marks, you'll find the two small indentations on the aft edge of the pulley that are the stock lead and trail marks.

First, take a flashlight and look for 2 notches on the inside edge of the pulley. Unless the pulley is non-standard, the timing notches should be present. If you find them, take a bit of airplane dope and put a dab of paint in each notch. Facing the engine, the notch to the right (i.e., clockwisemost) should be yellow, and the notch to left (counterclockwisemost) red. There ya go.
