My alternator bracket seems to be broken. There is a bolt on top of the bracket that broke. The only way I can tighten my alternator is by sliding it back on the bracket. When I feel the tension on the belt it seems pretty loose compared to the other belts. I think this is causing the alternator to not charge my battery correctly.
I alos replaced the alternator about 4 months ago because the other one was shot and now I think this one is going bad.

How is the belt supposed to be tightened normally? Does anyone know where I could find that bracket?
