Still cant figure it out!!!!! The alignment is off and one of the long brass bolts does not fit through the bottom hole on the P.S pump. I had to put it out side the bracket and pinch the black bracket against the pump then threaded the bolt on the lower silver piece. That was the easy part. Getting the silver piece was straight forward but that black piece makes NO SENSE! Maybe I have the wrong year bracket. As it sits now, it looks funny and the pump sits back 1/4 inch back from the rest of the pullies. I cant return the part because i scratched it up.
