Drive belt advice please?

I am trying to buy a replacement drive belt on line & it's proving hazardous to my health:confused:...... I must be having a blonde moment!
....1998 K11 1.0 litre - the belt for the alternator, the car is non power steering but with a/c. - the car is not here at the moment but I need to get it ordered. Which is the right belt please?
