I am wanting info on this. Did any of these trucks have full time 4wd? What about manual hubs? thanks

 

which years? and what about manual hubs?

 

When you talk about "these trucks", I'm assuming you're talking about first gens. The NP203 was available in Dodge trucks in the 1970s (roughly from '73-'79 IIRC). It was a full-time t-case, and vehicles equipped with it usually did not have manual locking hubs.
