Volvo Repair: Volvo 960 cam belt instulation, tdc mark, belt pulley

Question
Just gor a 1992 Volvo with the 3.0 DOHC 6 cyl engine.
Has a new cam belt hanging, not installed. I know it bends valves, and want to install the belt, so I can see how bad things are.
Cam pulley marks are near invisable. Believe I have the IN pulley mark, 2 teeth away from a letter "M", which is on the pulley face. Ex pulley mark, if I have found it, is about 6 teeth away from the "M", counter clockwise.
The crank cam belt pulley has no visable marks. Using a long screw driver, if #1 is at the grille end of the engine, TDC appears to be on top of a tooth, not down in the groove. If IN pulley mark is correct, I can string the cam belt from the IN pulley to verify crank position, but would rather know for sure. I see the TDC mark on the front engine cover. If I can verify what /where marks are to set it up, that will get me going.
Would appreciate any help you can give me.

Answer
CRANK MARK IS NOTCH ON THE TOOTH LINES UP WITH RAISED MLINE ON ALUMUNIM PIECE BEHIND PULLEY.THE CAM MARKS ARE 2 SMALL NOTCHES ONE ON EACH PULLEY THEY LINE UP WITH v SHAPED MARKES ON THE UPPER TIMING BELT COVER THAT HANGS OVER THE TOPS OF THE PULLEYS.THEY SHOULD BE AT ABOUT 2 LEFT PULLEY AND 11 OCLOCK FOR THE RIGHT PULLEY.

IF IT WAS RUNNING WHEN BELT CAME OFF PUTTING BELT ON IS A WASTE OF TIME.IT WILL NEED A NEW CYLINDER HEAD.
