I need to put together a wide DRW Dana 70 axle for my 4.88 geared work truck. I just bought an early series (early 1970's) CNC Ford Dana 70 with 4.88's for cheap. I know the early units had a .5 pinion offset and the new ones such as a 70HD have the .625 offset. Can I swap the ring/pinion from the early unit into a newer D70 axle?
