So my girlfriend's dad managed to blow a mainfuse changing an alternator. so its up to me to change the main fuse.. i thought it would be easy enough.. but the damn fuse is so brittle when i removed the bolt on the side the fuse basically fell apart.. but my question is where are the two main bolts that hold it in.. are they the two on the left hand side down that little crevis?

this is really urgent as i need to pick up my girlfriend in this car.. so i need to get it going.
