99 vs 99.5 - what is the date break?
What is the cutoff date between the two? I have heard that ones built 12/98 and later are 99.5. Is this correct? Also what is the best way to tell the difference if the door tag is missing? Thanks

Model Year 1999
Beginning in early 1998, Ford Motor Company began selling the "Super Duty" truck which replaced the older generation F250HD and F350. In addition, the F450 and the F550 was added to the line up to create a wide range of options for the light to medium light duty truck buyer. With the 99, a new generation of Powerstroke engines from Navistar debuted in the new truck that were more fuel efficient and quieter than their previous generations. 1998 Calendar year sales of the 1999 model and all remaining 98 stocks totaled just under 150,000 units in the diesel model alone. With very little competition from GM' Diesel and moderate competiton from Dodge Ram Cummmins line of diesels, the Super Duty had a field day. The main reasons? It was a Ford Product and many die hards bought the new model, it was the only crew cab diesel offered, and its design converted many owners of other brands.
Production Began
February 1998
Production Ended July 1999 (est)
Number of units made Unknown at this time
Diesel units 150,000 (est)
Model Year 1999.5
It really isn't a model year officially, but FoMoCo updated the engine and truck a little bit for better or worse.
Changes for the 1999.5:
Fender badge for the PSD removed, door badge added.
Lumbar seat deleted
New front-intake "cool-box" air filter box (Older models retrofitted to this style)
New down pipe
Bed body side molding removed.
Passenger side airbag standard across the line
Passenger lumbar removed
"Superduty" added to the rear tailgate badge for 350
Larger turbo
Catalytic converter removal
New injectors
Lower restriction intercooler
While most of the engine and power train specific items happened around 12/1/98 - 12/8/98, many of the "little things" such as the lumbar and badging happened at different times. If your truck was made after 12/8/98, You definitely have a "1999.5."
Most of the powertrain components were changed due to emissions. Other changes were to cut costs, for better or worse.
Hope this helped you.
