This is from the pirate 4x4 dana 60 front tech.
1979-89 versions had external style hubs, with the earlier versions with full-time NP203 Transfer cases having external drive flanges, and later models having external lockout hubs. The external lockout hub bolt pattern is 8 x 3.960". The 90-93 versions had internal style hubs just like the Chevy and lockout hubs. One caution with dodge applications, is you have to be careful to avoid the Dana 61 front axle. 1987-88 and 1991-93.5 Dodge D600 and D700 also came with Dana 61. More info on the Dana 61 later in the article.
Along with the Dana 61's, I would avoid the early 60 fronts with the closed knuckles and drum brakes. 74 and earlier I do believe. They aren't as strong as a later model.
