Bumper problem please help :D
 

I just bought this car the other day for only $850 it is a 99 mirage. runs GREAT does shake a little at about 40 and above but im figuring it is the alignment. but the bumper was ran into and is only being held up by two screws. i know nothing about what to do. any hints? i want to get it put back in the way it should be.
