Timing marks vg30e

[M30 Steve]

My sevice manual does not show TDC or degree increments on the crank pulley for ignition timing my vg30e. It is a model year 1990 M-30, I believe this engine is the same as the 260 or 280z late 80's early 90's. The specs. say 15deg. BTDC +or- 2deg. If you have any info or a pic it would be great.

Thanks, Steve
