1982 Toyota Pickup timing mark

Could you please tell me what the timing mark looks like and where it is on an 1982 Toyota Pickup engine 22R? Thank You Very Much Jim

Thank you for your answer but I am asking for my husband and this is what he needs to know. He needs the cam shaft sprocket setting the engine up for top dead center, does he use the dimple on the gear or the alignment pin on the cam shaft?Thanks again
