I have actually never seen a stock crew cab 4x4 without a front Dana 60. Sounds like someone did a swap job and swiped the front axle. The 700R4 sounds like a possible swap job as well. I am not aware of any overdrive transmissions in 1 tons until 1991 when the rare 4L80E appeared in the square Crew Cabs and ¾ ton Suburban’s.
