Yep! In the 90s Chevy came out with a medium duty truck known as the c3500hd, not to be confused with the c3500 found in their light duty pick up line. This was a 15,000# class 4 vehicle, three piece frame, Dana 80 10 lug rear, and many other heavy duty qualities. They were only available in 2wd unless.... You went to either Monroe or Quigley and paid a large price for them to add a Borg Warner 4470 transfer case, two new driveshafts, an oddly mounted carrier bearing, and the rare 10 lug Dana 70f. Monroe was the better of the two conversions whereas Quigley sometimes used Dana 60s up front with only 8 lug front hubs. In this case you could not use factory rims up front.
