Where are the bolts located for the starter on a 1991 Nissan Sentra?

I have a 94 Nissan Sentra but it's the same body style. My starter is located right below all the air intake hoses. the easiest way to find the starter is to take the airbox stuff out and then follow the ground wire from the negative end of the battery (the only wire leading off the negative end) to where it attatches to the transmission. The bolt that that wire attatches to is one of two bolts that attatches the starter to the transmission.
