taking starter off 99 taurus

anyone know how to get a starter off a 99 taurus? theres suposedly "2 bolts according to the haynes manual" but i get one out with a regular socket, and the other is like its broken off down in a hole, but in the haynes manual picture it looks the same, what tool is needed to back this "bolt" out? It's not really broken off in there i just dont know what tool to use to do this?

I figured it out, the other bolt was covered it oil buildup and dirt, what i saw was a lil stud that lined the motor up, my mistake... sure im not the only one thats done that =D
