What do i have

[Rob454]

hey guys I am very confused about what truck I have
1999 F250 superduty 4x4 Lariat package diesel 7.3

has square U bolts on the axle ( at least they look square the tops are not round. I have read the description of flat curved and rounded. Mine look flat
The diesel badges are on the door
has a build date of 12/98 there is no day just month and year
Cruise light comes on when you press the cruise button
Dealer replaced the hubs so i don't know what they were replaced with

I am trying to figure out if I have because i am looking into picking up one of those leveling kits that have a adjsutable track bar and its a set of mini leaf springs and u bolts to bring the front end up after the Ranch Hand bumper and winch i installed sagged my front end a bit so i have no idea if I need to order a early 1999 kit or a late 1999 kit

Anyplace that has actual pics depicting the differences besides just people describing the differences? I can take pics if it helps.
Thank you
Rob
