For the Ranger, I would say 95-97. Nicer interior than the 94 and older, and has pretty much bullet proof front suspension for being stock. For the Bronco 2, I would say whatever years were fuel injected. I really don't know about the Explorer. I like the first gen suspension, but it is just lacking everywhere else I think. And the fact that you could get a V8 in one makes the decision harder. I would probably get a V8 version so second gen on the Explorer. Got to go old school for the F-150 and say the 79-79. I love those trucks. Second place for the F-150 would be the 92-96 style. Gotta say the same thing for the fullsize Bronco as the F-150.
