According to all the research I’ve done, in 1989 Ford switched to a Dana 50 IFS from the Dana 44 IFS. However, my 89 has a Dana 44. Is it possible that because the manufacture date of my F250 is February of 89, that it still had parts from the 1988 models?

8600 lbs was the highest GVWR offered on F-250s of that era, and a lot of 8600 lb GVWR F-250HDs used the Dana 44HD front axle. The Dana 50 was used primarily with a snow plow package or on crew cabs (maybe SuperCabs?). And of course the Ford tendency to use what they had available, so any time you think there's a hard-and-fast rule you'll find someone with a truck that breaks the rule.
But yes, seeing the hubs will tell the tale. 44 hubs have an OD that's quite a bit smaller than the center hole in the 8 lug wheels. Dana 50s pretty much fill the hole.

supercab, crew cab and diesel F250's all got D50's. all others could have either the D44 or D50.
at the body shop we had two 89 F250's. sequential serial numbers, ordered by the same company as identical optioned trucks. one had a D44, the other had a D50.
