whats the timing mark look like

on the flywheels of a 1960 pan,is it a dot or a straight groove?I have a manual but it only goes to 57,gonna have to get a new one sometime..............

If memory serves me, it is the slash for the front cyl and a dot for the rear

1960 has the dual points, so there's a front and rear mark, but IDK what they look like.
