Brand new idler arm, lots of play

Rebuilt the whole front end of my '72 dart and the idler has all this up and down play in the mounting bracket.. I can wiggle the wheel back and forth and make the idler move up and down within its mounting bracket..i know this can NOT be normal..I have a video but dont know how to get it here..i tried to do it like i would to add a photo but said the file was too large.
