I found a tidbit on HD44s (heavy duty D44 3/4ton 8-lug axle). If the manual locking hub bolts onto the wheel hub, it's an HD44. For instance, my K20 Sub's HD44 has Spicer locking hubs that each bolt on with 6 allen bolts. If the locking hub attaches to the wheel hub with a snap ring on the outer stub axle and studs with cone washers & nuts, it's not a heavy duty D44.

The HD44s have a spindle all their own that uses larger bearings than lesser D44s. All the better for load-bearing capability [pardon the engineering pun

].
