this is what I think happened... I think changing the mono leaf to a 5 leaf multi leaf changed the pinion angle.. that would explain the u bolts tilting back so much... I'm going to take it apart and put a 4 degree wedge in the perch and center the tires in the wheel well and see where that leaves me...

ok.. that was a fail... .. I'm ordering new , new springs.. on the bright side.. I was able to paint the whole underside while this project was going on.. lol..
