Took the ghost (1999 F-150 Lariat 4WD) to the shop for alignmet due to some funky wear on drivers front. they called me back before i got back to my office and said that they could not do alignment due to bad lower BJ on both sides and bad upper control arm on drivers side. I told them that I would do the work myself but they said to put an eccentric kit (caster and camber kit) on the new upper arm. got all the parts but have zero instructions on how the eccentric kit is supposed to go on. Any ideas?
