I think its just the size of the king pins they would be bigger in diameter for the f250

They do make a 3" drop spindle kit for the 70's ford but I don't I can't remember who sold the kit. Try a google search for the kit.

Welcome to FTE

Speculating on what fits what is guesswork only. It doesn't prove a damn thing.

OP...Just where exactly did you get your info? It wasn't from any Ford truck parts catalog.

1975/79 F250 Regular Cabs with a GVW between 6200 & 6900 lbs. use the same I-Beams as 1975/79 F100/150's use.

The king pins are also the same for this application.

IF the 1975/79 F250's GVW doesn't fall between 6200/6900 lbs., or if the truck is a Super or Crew Cab...then the I-Beams are not the same as a 1975/79 F100/150, neither are the king pins.
