Crank lines up with the pick up lug next to the v grove in crank pulley on a YB, also from your picture the dizzy pulley arrow should be at about 1 o clock poistion, there should be a dot indent in casing behind the pulley.
I fitted a new belt to my own, car today, still fresh in my mind! You should be able to get the camshaft arrows to face each other and be inline with facing edge of rocker cover , can take a few goes! cheers
