 Ted: I second ALB's advice. But I modify: If the screws were loose already, first pull the arms off and see if they were on straight. I put one on whacked 00 degrees out when I pulled springs out of my car. Almost didn't notice, but the grub screw wouldn't seat. So you might have just loose arms. Or you might (unlikely, but maybe) have trailing arms that are on wrong. Or you might have dropped spindles with beam adjusters that are designed to drop it further--a common error, I'm betting.
