early 99 f-350 suspension kit

f-350 build date 06/98... what is the difference in the lift kit between early model 99 vs later 99?

Trucks built before 3/31/99
square front ubolts
smaller sector shaft so smaller spline pitman arm required
small mounting holes for track bar so smaller holes in track bar bracket



After 4/1/99
Semi Round front ubolts
larger spline pitman arm
larger bolts in track bar

there was some sway bar link changes after 2000 also. so some kits use a drop bracket and some use a longer link and some use a relocation bracket.
