Finally gotten my motivation back, and been diving in out in the garage. Started to narrow the mid 70's dana 44HD that I'll be using under my F-3. Not quite done yet, but hoping by the end of the weekend I can get it back together (minus the axle shafts which will be headed to a machine shop).

And just to give some specs, the driver side will be 2.5 narrower, and the passenger 5.5 inches. The finished project will result in and axle 1 inch wider (WMS to WMS) than the stock front axle
