    perhaps if you cannot see the mark, simply bust out the ol' protractor and paint pen, make your own pointer and crank timing mark exactly 180 degrees out on the BOTTOM of the pulley, jack the front of the vehicle up, and point your timing light there.

    While you have the paint pen out, you might want to scribe a line from inner harmonic balancer hub through the rubber isolator band, to the outer hub. Check it after running the engine several minutes. I have seen several slip, making static timing impossible.
