I do not know which of the 4 bolts to choose from, but I would assume that if the dipstick looks level and straight, you have the correct hole.
Actually I do know, but easier if you trial fit yourself. With 4 holes to choose from, up and down, closest to the finundal valve, half past the firewall speed sensor is too complicated.
