I'm replacing the timing belt on my 86 325e
Big surprise doesn't have any mark on the cam pulley.
What do I do? Should I align the two screw holes from the distributor rotor with that mark?

Still hope,
Should I align the two screw holes from the distributor rotor with the
mark on the head or align the two holes in the pulley that you align to see the bolts that
Serve to remove the distributor.
The pulley is a steel type not aluminium
made like this ^^^^^ no thick area where you can see any marks.
