Thanks very much for the information.
Do the older style arms need to be greased more often?
Do the arms with rubber bushings provide a smoother or less jarring ride?

As long as you’re not trying to interchange a 1 ton arm with the bolt on setup they will swap out. Lowers I believe the bolt holding the shaft onto the crossmember got larger in diameter. Uppers are a direct bolt on. As far as greasing goes it’s no different than any other metal on metal wear item. Grease items when doing usual maintence and it shouldn’t matter.
