Need hubs for my 78 since it didn’t come with any when I got it. It appears to me that there are two kinds of axle shafts that came in the front. One with the snap ring groove closer to the outside, and one closer to the inside. Mine are the ones closer to the inside. My buddy has the same axle shafts as I do and his Warn hubs do not fit as a result. What hubs will fit? Thanks in advance!

 

I would wait for someone with more knowledge than me, but you might have the full time 4wd with the NP 203 transfer case that never had manual locking hubs. Every 1966 through 1979 Bronco I have had (part-time)uses the same locking hubs with an snap ring groove toward the outside of the hub plus a external snap ring that goes on the axle. I have never had a full-time but I know there are kits to make them part-time.
