Dave and I just got off of the phone discussing his work on comparing the front and rear carrier and ring and pinion dimensions. To sum it up, the whole 3rd member with carrier will fit the front axle but some kind of bracket will need to be fabricated to prevent axle wrap.

Another possability that [color:"blue"] might [/color]work would be to put the rear carrier and it's 7.5" ring gear into the front 3rd member housing [color:"blue"] and [/color]put the pinion gear from the rear in too. We don't know for sure if the pinion will fit but the bearings have the same part number.
